A horizontal cylindrical segment is a section of a horizontal cylindrical tank that is partially filled with fluid and is defined by a single plane that is parallel to the cylinder's axis of symmetry.
What is the location of the horizontal cylinder?By first calculating the area, A, of a circular section and multiplying it by the length, l, you may determine the filled volume of a horizontal cylinder tank. The area of the circle, which is drawn in grey, is given by
A = (1/2)r2( - sin),
where = 2*arccos(m/r) and is a radian.
V(segment) is therefore equal to (1/2)r2( - sin)l.
Oblique Cylinder: An oblique cylinder is one in which one of the bases is sideways and the axis is not at a right angle to the base.
V=Bh or V=r2h is the formula for a cylinder's volume.
The cylinder measures 8 cm in diameter and 15 cm in height. The equation V=r2h should be changed to 8 for r and 15 for h.

A 1 meter tall vertical column of water exerts a static pressure of 9.8 kpa. You would need to put 127kpa - or 13 times 9.8kpa - at the hose's nozzle exit to move water 13 meters up a vertical axis.
The final sentence is crucial since it clarifies that this pressure is not what the pump or the mains require.
The length of the hose, friction inside the hose, any valves, or restriction nozzles all greatly limit the pressure between the supply/pump and the nozzle, which in turn affects the pressure required at the mains or the pump.

What is Electrical resistance welding basic principles
According to the basic principles of Electrical Resistance Welding, Resistance welding is used to fuse two metals together. See further explanation below.
Principles of Electrical resistance weldingIt is to be noted that Electrical Resistance Welding comprises a welding head that exerts pressure and holds the metal between its electrodes, as well as a welding power source that applies electric current to the metal to be welded. When force is exerted, resistance creates friction heat.
A weld is a metal coalescence formed by heating to an appropriate temperature with or without pressure, and with or without the introduction of a filler substance.
Resistance welding bonds are classified into three types:
solid state, fusion, and reflow braze.Different materials having dissimilar grain structures, such as molybdenum to tungsten, are bonded utilizing a relatively short heating time, high weld energy, and high force in a solid state bond, also known as a thermo-compression bond.

Water is flowing into a conical vessel 15 cm deep and having a radius of 3.75 cm across the top. if the rate at which the water rises is 2cm/seconds, how fast is the water flowing into the conical vessel when the water is 4 cm deep?
The water is flowing into the conical vessel at a rate of 6.28 cm³/s
The formula for the volume of the conical vessel can be given as;
V = 1/3π(r²)h
Here h represents height and r represents radius.
As,
15/3.75 = h/r
Cross multiplying;
15r = 3.75h
r = 3.75h/15
So we can get the volume in terms of height as follows;
V = 1/3π(3.75h/15)²(h)
V = 1/3π(14.0625/225)h³
V = 14.0625πh³/675
As we have to find how fast the water is flowing in the conical vessel it can be represented as; dh/dt
Now
dV/dt = dV/dh × dh/dt
dv /dt = d/dt [14.0625πh³/675] = 14.0625π/675 (3h²) dh/dt
Substituting the values;
2 = 14.0625π/675 (3)(4²) dh/dt
2 = 3.14 dh/dt
dh/dt = 6.28 cm³/s
Hence, the water is flowing into the conical vessel at a rate of 6.28 cm³/s

assuming complementary inputs are available, the minimum number of transistors needed to realize a two input xor gate is:
Assuming complementary inputs are available, the minimum number of transistors needed to realize a two input xor gate is 4.
If two inputs work well together in the production process, they are said to be complements. Since the inputs are used in fixed proportions, if the price of one input lowers, more of it will be sought after, increasing the demand for the other input.
In this study, a model of anticompetitive exclusive contracts with complimentary inputs is built. A downstream company converts a variety of complementary inputs into finished goods. When complementary input providers hold a dominant position in a specific input market, upstream competition price within that market benefits both the downstream firm and the complementary inputs providers by driving up complementary input prices.
Thus, even when entry that is socially optimal is permitted, the downstream firm is unable to generate higher profits. Therefore, even in the absence of scale economies, downstream competition, and relationship-specific investment, the inefficient incumbent provider can prevent socially efficient entrance by employing exclusive contracts.

Find the Transfer Function using the Block Diagram.
The transfer function from the given diagram is given as follows:
[tex]\frac{X(s)}{F(s)} = \frac{s + 3}{s + 13 + G(s)}[/tex]
How to find the transfer function of a system?The transfer function of a system is given by the ratio between the output X(s) and the input F(s), as follows:
H(s) = X(s)/F(s)
From the initial subtraction operation, we have that:
F(s) - X(s) = E(s)
In which E(s) is the error of the system.
After the subtraction, the error is measured as follows, considering the perturbation G(s) and the multiplication of the blocks:
E(s) = (10 + G(s))(1/(s + 3))X(s)
Replacing this into the initial function, we have that:
F(s) - X(s) = (10 + G(s))(1/(s + 3))X(s)
Using latex for better visibility of the operations:
[tex]F(s) = X(s) + \frac{10 + G(s)}{s + 3}X(s)[/tex]
Using X(s) as the common term, we have that:
[tex]X(s)\left(1 + \frac{10 + G(s)}{s + 3}\right) = F(s)[/tex]
[tex]X(s)\left(\frac{s + 3 + 10 + G(s)}{s + 3}\right) = F(s)[/tex]
[tex]X(s)\left(\frac{s + 13 + G(s)}{s + 3}\right) = F(s)[/tex]
Hence the transfer function is given as follows:
[tex]\frac{X(s)}{F(s)} = \frac{s + 3}{s + 13 + G(s)}[/tex]
