Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.5-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kPa (gage) in the tank. If the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top.
Answers
The discharge rate of the supply of water to the roof top is;
V' = 9.8641 L/s
What is the Discharge Rate?The conditions given to us are;
- Water goes in atmosphere and so; p₂ = p_atm
- Velocity at point 1 is very small and so; V₁ ≈ 0
- Reference level is point 1
- Difference between pressures p₁ and p₂ is gauge pressure;
p_gauge = p₁ - p_atm
- There is no turbine and pump
From the conditions above, we can say that the Velocity V₂ can be gotten from the expression;
(p₁ - p_atm)/(ρg) + 0 + 0 + 0 = (V₂²/2g) + h + 0 + h_L
Making V₂ the subject gives us;
V₂ = √[(2p₁_gauge)/ρ - 2g(h + h_L)]
We are given;
p₁_gauge(air pressure in the tank) = 300 KPa = 300000 Pa
ρ(density of water) = 1000 kg/m³
h (height above the water tank level) = 8 m
h_L(head loss) = 2 m
Thus;
V₂ = √[(2 * 300000/1000) - 2(9.8)(8 + 2)]
V₂ = 20.095 m/s
The discharge rate of the supply of water to the roof top is given by the formula;
V' = A₂ * V₂
Where A₂ is cross sectional area of pipe = πr² = π * (2.5/200)² = 4.90874 * 10⁻⁴ m²
Thus;
V' = 20.95 * 4.90874 * 10⁻⁴
V' = 9.8641 L/s

what is the mda and visibility criteria for a straight-in loc/dme rwy 21 approach at portland international in a category b airplane? a. 700 ft. msl; visibility 1 nm. b. 1,120 ft. msl; visibility 1 sm. c. 700 ft. msl; visibility 1 sm.
Answers
b. 1,120 ft. MSL; visibility 1 sm.
According to the Federal Aviation Administration (FAA) Instrument Procedures Handbook, the minimum descent altitude (MDA) for a straight-in localizer/distance measuring equipment (LOC/DME) runway 21 approach at Portland International Airport in a category B airplane would be 1,120 feet above mean sea level (MSL). The visibility requirement for this approach would be 1 statute mile (SM). Therefore, the correct answer to your question is: b. 1,120 ft. MSL; visibility 1 sm.
MDA INFORMATIONIt's important to note that the MDA and visibility requirements for an approach can vary depending on the specific approach being flown and the equipment available at the airport. It's also worth mentioning that the MDA and visibility requirements must be met to fly the approach. If the actual conditions at the airport are below these minimums, the approach cannot be flown, and the pilot must either execute a missed approach or proceed to an alternate airport.
The minimum descent altitude (MDA) is the lowest altitude that an aircraft is allowed to descend to during an instrument approach. It is typically expressed in feet above mean sea level (MSL) and is established to provide the pilot with an apparent visual reference of the approach path and the surrounding terrain. The MDA is determined based on the type of approach being flown and the equipment available at the airport.
The MDA is not a decision altitude (DA), which is the altitude at which the pilot must decide to either land or execute a missed approach. The DA is typically higher than the MDA and is based on the height of obstacles in the approach path. It's important to note that the MDA is a minimum altitude, and the pilot is not required to descend to the MDA unless it is safe to do so. If the pilot cannot see the runway or the required visual references at the MDA, a missed approach must be executed. In other words, the MDA is the minimum altitude that must be maintained during an instrument approach unless the pilot can see the runway or the required visual references, in which case the pilot may continue the approach and land.

Answers
Answer:
These small devices are easily patched by the user, whether consumer or industrial.
One of the main challenges with IoT devices is that they are often difficult or impossible to update or patch. Unlike traditional computers or smartphones, which can be easily updated with security patches and other software updates, many IoT devices are not designed to be easily updated by the user. This is because they may have limited processing power, memory, or storage, and may not have the capability to download and install software updates. As a result, many IoT devices are vulnerable to security threats, and attackers may be able to exploit vulnerabilities in these devices to gain access to an IoT network. In order to protect against these threats, it is important for device manufacturers to focus on security when designing IoT devices, and for users to carefully consider the security of the devices they purchase and use.

The bottom hole in the dam is blocked by a flat rectangular shield with a width of -6 m. The water depth in the upstream h1 = 23 m, the depth in the downstream h2 = 11.5 m, the height of the bottom hole t = 17.25 m, the angle of inclination a = 40 °. The sewing can rotate around the axis, which is projected to point A. Determine the force T required to raise the shield.
Answers
To determine the force required to raise the shield, we can use the principle of static equilibrium.
In this case, the shield is being acted upon by two forces: the weight of the shield, which is a force acting downward, and the force T, which is a force acting upward.
The weight of the shield can be calculated using the formula: W = mg, where W is the weight, m is the mass of the shield, and g is the acceleration due to gravity. The mass of the shield can be calculated using the formula: m = ρV, where ρ is the density of the material the shield is made of and V is the volume of the shield.
The volume of the shield can be calculated using the formula: V = Bh, where B is the width of the shield and h is the height of the shield. In this case, B = -6 m and h = t = 17.25 m, so V = (-6 m)(17.25 m) = -106.5 m^3.
Plugging this value into the formula for mass, we get: m = ρ(-106.5 m^3).
What is principle of static equilibrium?The principle of static equilibrium states that the sum of the forces acting on an object must be equal to zero in order for the object to be in equilibrium.
As a result, the force T required to raise the shield can be calculated using the principle of static equilibrium. We can set up the following equation: T - W = 0, where T is the force acting upward and W is the weight of the shield acting downward.
Substituting in the values for T and W, we get: T - (m*g) = 0.
Solving for T, we get: T = m*g.
Therefore, the force required to raise the shield is equal to the mass of the shield multiplied by the acceleration due to gravity.

The following are the steps to design a double-reduction gear train:
What is reduction?
Reduction is the process of decreasing something or making it smaller in size, amount, degree, or value. It is a fundamental concept in mathematics and economics, but it can also be applied to any type of process, from manufacturing to philosophy.
Reduction can refer to a process of simplification, a change in complexity, or a decrease in the amount of material needed or used. Examples of reduction include reducing the number of steps in a process, reducing the amount of data used to make a decision, or reducing the cost of production. In many cases, reduction can be used to improve efficiency and productivity, or to create a more sustainable system.
1. Determine the gear ratio: The gear ratio is the number of teeth on the input gear (a) divided by the number of teeth on the output gear (C). In this case, the gear ratio would be 1176/324 = 3.65.
2. Calculate the input The following are the steps to design a double-reduction gear train:
1. Determine the gear ratio: The gear ratio is the number of teeth on the input gear (a) divided by the number of teeth on the output gear (C). In this case, the gear ratio would be 1176/324 = 3.65.
2. Calculate the input torque: The input torque is the product of the input power and the speed of the input shaft, or InPwr*InSpd. In this case, the input torque is 20*1176 = 23520 in-lbs.
3. Determine the output torque: The output torque is the product of the output power and the speed of the output shaft, or OutSpd*Ang. In this case, the output torque is 324*25 = 8100 in-lbs.
4. Calculate the center distance: The center distance is the distance between the center of the input gear and the center of the output gear. This distance is determined by the number of teeth on the gears, the gear ratio, and the pitch of the gears. In this case, the center distance is 11/(√3.65) = 6.45 inches.
5. Determine the shaft size and bearing size: The shaft size is determined by the torque rating of the shaft and the bearing size is determined by the shaft size. In this case, the shaft size would be 2.50E+08 in-lbs and the bearing size would be 11/2 inches.
6. Design the gears: The gears must be designed to fit the shaft size and bearing size. The number of teeth on the gears must match the gear ratio. In this case, the input gear would have 1176 teeth and the output gear would have 324 teeth.
7. Assemble and test the gear train: Finally, the gear train must be assembled and tested to ensure that it meets the design parameters.

Operations needed to comply with requirements under: are not subject to the rules of this component : Part 121, 125, 129, 135, and 137,
An air-breathing jet engine, the turbojet is frequently found in airplanes. It is made up of a gas turbine and a nozzle for propulsion. The gas turbine has a compressor, a combustion chamber, a turbine, and an air inlet with inlet guiding vanes (that drives the compressor). Fuel combustion in the combustion chamber heats the compressed air from the compressor before allowing it to expand via the turbine. The propelling nozzle expands the turbine exhaust, which is subsequently accelerated to a high speed to provide push. In the late 1930s, two engineers, Hans von Ohain in Germany and Frank Whittle in the United Kingdom, independently developed the idea into workable engines. Turbojets are only helpful in aviation because of their poor efficiency at low vehicle speeds. In rare instances, turbojet engines have been utilized to power vehicles other than airplanes, usually in an effort to break land speed records. When a vehicle is "turbine-powered," it most often means it has a turboshaft engine, a modified gas turbine engine that uses a second turbine to power a revolving output shaft. These are typical in hovercrafts and helos. On Concorde and the longer-range versions of the TU-144, which had to spend a lot of time travelling supersonically, turbojets were used.

A. With dynamic NAT, the initial packet flow from the inside network causes the entries to be produced. Network address translation (NAT) functions by converting private addresses to the NAT router's public address. -Hosts connected to the private network share a pool of addresses or the NAT router's IP address. -The NAT router associates private IP addresses with port numbers. Choosing the internal and outside interfaces is the initial stage in NAT configuration. Beyond that, whether you are configuring static NAT or dynamic NAT affects the setup. Simply add the necessary mapping entries to the NAT table for static NAT.

Which of the following is an example of proprietary system software?LinuxMicrosoft Internet Explorer Microsoft OfficeMicrosoft Windows
Answers
Answer:
Microsoft Windows
Explanation:
Microsoft Windows is an example of proprietary system software. Proprietary software is software that is owned by a specific company or individual and is typically only available for use through a license from the owner. This is in contrast to open-source software, which is freely available for anyone to use, modify, and distribute. Microsoft Windows is a proprietary operating system developed and owned by Microsoft Corporation. It is not open-source and can only be used by individuals or organizations who have purchased a license from Microsoft.
Linux, Microsoft Internet Explorer, and Microsoft Office are not examples of proprietary system software. Linux is a free and open-source operating system, and Microsoft Internet Explorer and Microsoft Office are both proprietary software programs developed and owned by Microsoft Corporation.
Calculate Mn for the distribution below. (Enter number only.)
• 2 at 100,000 g/mol • 4 at 200,000 g/mol • 6 at 300,000g/mol • 3 at 400,000g/mol • 1 at 500,000 g/mol
Answers
The number average of molecular weight (Mn) for that distribution is 281,250.
How to calculate Mn?Ni = Number of molecules in order i
Mi = Molecular mass in order i
Number average of molecular weight or Mn is a average molecular weight for each individual macromolecules. Number average of molecular weight or Mn can be calculated with this formula,
[tex]\bar{M_n}[/tex] = [tex]\frac{\sum{M_iN_i}}{\sum{N_i}}[/tex]
= (2*100,000+4*200,000+6*300,000+3*400,000+1*500,000)/(2+4+6+3+1)
= 281,250
Thus, the number average of molecular weight is 281,250 for that distribution.

please solve using c++ and the Backtracking Recursion method
must use the starter code(link) down below
Given a positive integer n, write a function that finds all ways of writing n as a sum of nonzero
natural numbers. For example, given n = 3, you’d list off these options (how these 4 terms ordering
does not matter):
3 : 1 + 2; 2 + 1; 1 + 1 + 1
In particular, your task is to finish the following function in the starter code

Answers
Backtracking is an algorithmic strategy for solving problems recursively by trying to create a solution progressively, one component at a time, and discarding those solutions that fail to fulfil the constraints of the issue at any point in time.
Recursion is used by backtracking to address its issues. To achieve this, it looks into every scenario that might arise from an issue until the best and most practical answer is discovered. When a function calls itself repeatedly to break an issue into smaller sub-problems, it engages in recursion and eventually reaches the base case. Backtracking is a generic algorithmic strategy that takes into account looking through each and every combination in order to address a computational issue. By calling a duplicate of itself and resolving the original problem's smaller subproblems, a recursive function solves a specific problem. Every time we go back, we remove the options that aren't going to lead to the solution and move on to the options that could.

You should display the signal at the various stages of processing. Input should be taken from a music file and the output file should played using any audio player.
Answers
The correct answer is MATLAB CODE for design envelope detector for demodulating AM signal
An electrical circuit known as an envelope detector, sometimes known as a peak detector, receives an input of a (relatively) high-frequency amplitude modulated signal and outputs the original signal's demodulated envelope. By mulitpiling the carrier and message signals, AM is achieved. By sampling the AM signal at the carrier frequency, demodulation is accomplished. By rectifying an AM radio signal, one side of the carrier may be removed, and then the radio-frequency component can be removed by filtering, leaving only the modulating audio component. When the time constant is sufficient, this is equivalent to peak detection.
