To determine the required insulation thickness, you will need to use the heat transfer equation, which states that the rate of heat transfer through a material is equal to the product of the heat transfer coefficient, the surface area of the material, and the temperature difference between the two sides of the material.

The temperature difference between the chilled water and the ambient air is 30°C - 8°C = 22°C.

The surface area of the pipe is given by the formula for the surface area of a cylinder:

A = 2πrL

where:

r = the radius of the pipe

L = the length of the pipe.

The radius of the pipe is 5 cm / 2 = 2.5 cm = 0.025 m.

The surface area of the pipe is therefore A = 2π(0.025 m)(150 m) = 7.85 m²

The heat transfer rate through the insulation is given by: Q = (kA)(ΔT)/d, where:

Q= the heat transfer rate,

k = the thermal conductivity of the insulation,

A = the surface area of the pipe,

ΔT = the temperature difference between the chilled water and the ambient air,

d = the thickness of the insulation.

Rearranging this equation to solve for d, the thickness of the insulation, we get:

d = (0.05 W/m·°C)(7.85 m²)/(9 W/m²·°C)(22°C) = 0.03 m = 3 cm.

Therefore, the required thickness of the insulation is 3 cm.

To determine the expiration date of the last annual aircraft inspection, a person should refer to the aircraft maintenance records.

What are aircraft maintenance records?

Aircraft maintenance records include information about the work done to the aircraft, the date it was finished, the signature of the maintenance team, information about the FAA certificate, and the certificate number and signature of the person who put the aircraft back in service. The maintenance records mentioned in this rule can be simplified into two groups: permanent records and expiring records.

Permanent records are those maintenance logs that need to be retained and kept up-to-date for the aircraft forever. They act as a record of every maintenance action that has taken place during the lifecycle of the aircraft. It also functions as a tool for figuring out whether an aircraft has received all necessary maintenance and is in a state that allows for safe flight.

Technician b is correct. According to Technician B, the majority of engine bearings have an aluminum shell for strength and are covered in a tin-lead alloy.

For street and performance engines, the generally acknowledged norm that most crankshaft manufacturers prefer is 0.0010-inch for every 1-inch of journal diameter. Therefore, the bearing clearance for a 2.45-inch small-block main journal would be 0.0024-inch.

The crankshaft journal's outer diameter is measured using callipers. A dial bore gauge is used to measure the bearings' inner diameter. Both rod bearings and main bearings are measured with the bearings mounted in the respective connecting rods and main bores, respectively.

A thin calibrated plastic strip serves as a plastic gauge. It can be used to measure gaps and monitor bearing clearance. It is utilized at locations on crankshaft or connecting rod bearings where a micrometre measurement is required quickly.

(a) It will take about 4.8e-5 seconds for the surface to reach a safe-to-touch temperature of 42 °C.

(b) The corresponding temperature at the plastic/wood interface will be 200 °C, since this is the initial temperature and the interface is assumed to be adiabatic.

To solve this problem, we need to use the heat equation, which describes how heat flows through a material:

∂T/∂t = α ∂²T/∂x²

where T is the temperature, t is time, x is position, and α is the thermal diffusivity.

To solve this equation, we need to know the boundary conditions and initial conditions. In this case, the boundary conditions are the surface temperature (42 °C) and the temperature at the plastic/wood interface (200 °C). The initial condition is the initial temperature distribution, which is uniform at 200 °C.

First, let's find the convective heat transfer coefficient, k, using the relationship:

h = k / d

where d is the thickness of the plastic coating and k is the thermal conductivity.

Substituting the values given in the problem, we find that

k = 0.05 W/m-K.

Now, let's solve the heat equation using these values. To do this, we need to rearrange the equation to solve for t:

∂T/∂t = α ∂^2T/∂x^2

∂t = (α ∂^2T/∂x^2) / ∂T

t = ∫ (α ∂^2T/∂x^2) / ∂T dx

We can simplify this equation by assuming that the temperature change across the thickness of the plastic coating is small, so that ∂^2T/∂x^2 can be approximated as T''/d^2. Substituting this and the values for the other parameters gives us:

t = ∫ (α T''/d^2) / ∂T dx

= ∫ (α / k) dx

= (α / k) x

To find the time it takes for the surface to reach a safe-to-touch temperature of 42 °C, we need to solve for the time it takes for the temperature at the surface to drop from 200 °C to 42 °C. Substituting these values and the values for the other parameters gives us:

t = (1.2e-7 m2/s / 0.05 W/m-K) (2 mm)

= 4.8e-5 s

Since all processes have a finish value of true, the safe sequence is P2, P3, P1. Therefore, the correct answer is (B) P1, P2, P3.

To find the safe sequence using the Banker's algorithm, you need to perform the following steps:

Using these steps, we can find the safe sequence for the given scenario as follows:

Need matrix:

P1: 3-2=1, 3-3=0, 3-3=0

P2: 2-1=1, 1-1=0, 0-0=0

P3: 1-1=0, 1-1=0, 1-0=1

Work array: [2, 1, 1]

Finish array: [false, false, false]

Step 1: Process P2 has a need of [1, 0, 0] which is less than or equal to the work array, so it can be allocated resources. Update work array to [2-1=1, 1-0=1, 1-0=1] and set finish[P2]=true.

Work array: [1, 1, 1]

Finish array: [false, true, false]

Step 2: Process P3 has a need of [0, 0, 1] which is less than or equal to the work array, so it can be allocated resources. Update work array to [1-0=1, 1-0=1, 1-1=0] and set finish[P3]=true.

Work array: [1, 1, 0]

Finish array: [false, true, true]

Step 3: Process P1 has a need of [1, 0, 0] which is less than or equal to the work array, so it can be allocated resources. Update work array to [1-1=0, 1-0=1, 0-0=0] and set finish[P1]=true.

Work array: [0, 1, 0]

Finish array: [true, true, true]

To add a method calculate pay() to the employee class. the method should return the amount to pay the employee by multiplying the employee's wage and number of hours worked, check the code given below.

In object-oriented programming, a class is a template definition of the method(s) and variable(s) in a particular kind of object. As a result, an object is a unique instance of a class and contains real values rather than variables.

The class is one of the core ideas in object-oriented programming. The following are some essential ideas about classes:

A class's subclasses are able to take on all or some of its parent class's characteristics. In relation to each subclass, the class becomes the superclass.

Subclasses can define their own methods and variables independently of their superclass as well.

The least amount of coordinates required to specify each point within a mathematical space or object is known as its dimension. A line therefore has a dimension of one since only one coordinate is required to identify a point on it, such as the point at 5 on a number line. In order to specify a point on a surface, such as the perimeter of a cylinder or sphere, two coordinates are needed; for instance, both a latitude and a longitude are needed to pinpoint a point on the surface of a sphere.

Grain diameter (d) = 5.6 × 10⁻² mm = 5.6 × 10⁻⁵ m
