Answer:

When you build a compressor that is supposed to run in an enclosed system you want the coolant medium (and the lubricants) in this system to function optimally during the service life of the system.

First of all, the coolant medium has a tendency to absorb water and this moisture can be aggressive on the internal components of the compressor so you want to remove this once the system is sealed.

Second, you want to filter out any particles that may shorten the life of the system.

Those are the two purposes of the liquid line filter drier in the refrigeration system.

Explanation:

Based on the information, the tube thickness that should be used is 3.18 mm.

Power = Torque * Angular velocity

100 kW = Torque * (2 * pi * 36 Hz)

Torque = 2212.14 N-m

In this case, the polar moment of inertia is:

J = pi * 50⁴ / 32 = 196250 pi mm⁴

Maximum shear stress = Torque / J

Maximum shear stress = 2212.14 N-m / 196250 pi mm⁴ = 0.0499 MPa

Tube thickness = 2 * ✓(60 MPa / pi * 50²) = 3.18 mm

Therefore, the tube thickness that should be used is 3.18 mm.

In low airspeed, high power, and high angle of attack flight conditions, torque effects are more pronounced in a single-engine airplane. Therefore, option A is correct.

A torque is a rotational or twisting force that tends to cause rotation around an axis or pivot point. It is a vector quantity, meaning that it has both a magnitude and a direction.

In flight, torque refers to the twisting force produced by an airplane's engine and propeller as they rotate. which can cause the airplane to roll or sheer in the opposite direction. Thus, option A is correct.

Answer:

a) x = 5.7791 m ( this a turbulent flow )

b) x = 0.04 m ( this is a Laminar flow )

Explanation:

For Air, take

p = 1.2 kg/m³ and u = 1.8×10⁻⁵ kg/m³

So for A , x = 10 cm

Guess turbulent flow;

(Sturb / x) = (0.16 / (p∪x / u)^1/7)

we substitute

(0.1/x = 0.16) / ( 1.2 × 15 × x / 1.8×10⁻⁵)^1/7

x = 5.7791 m

CHECK

Re = (1.2 × 15 × 5.7791) / 1.8×10⁻⁵ = 5.779×10⁶

Therefore this a turbulent flow

for B, x = 1mm

Guess Laminar flow

(S-laminar / x) = ( 5 / (Reₓ)^1/2)

x = (Stutb)²p∪ / 23u

x = ((0.001)² × 1.2 × 15) / (25 × 1.8×10⁻⁵)

x = 0.04 m

CHECK

Re = (1.2 × 15 × 0.04) / (1.8×10⁻⁵)

= 40000

Therefore  this is a Laminar flow

The approximate emmission of Crimson is 620 to 700 nm

We would have to identify the wavelength that are emitted by the strontium.

In the strontium test, the observations would be based on the flames that are crimson red.

In the color wheel, the color with the highest wavelength is red at 620 to 700 mm.

3. The original color that is present in the test comes from when metal salt is heated. This usually causes its outer electrons to be excited, falling back to different energy wavelength in the spectrum.

Higher wavelength = loosely bound electron in the outer shell so that less energy is required.

The metals are red when they are burnt. The red color is the one with the highest wave length.

This is defined as the existing distance that is found between waveds. These could be sound or electromagnetic waves.

Technical drawing

Explanation:

The drawings reflect what the project specifications are unlikely to cover

The answer is ,the equivalent force is 600 N and the equivalent couple moment is 900 Nm, both acting at a distance of x = 3/2 m from point O.

Equivalent force is a single force that replaces a system of forces, and has the same effect on an object or structure as the original system of forces. It is used to simplify the analysis of complex systems by reducing them to a single force that is easier to work with.

In this problem, we have a loading consisting of a distributed load of 200 N/m, as shown :

           |<--3m-->|

     |---------|

     |         |

     |         |

200 N/m|         |

     |         |

     |         |

     |---------|

         4m

To find the equivalent force and couple moment, we first need to find the location of the force. Since the loading is distributed, the force must act at the centroid of the loading, which is located at the midpoint of the loading:

x = 3/2 m

So the force must act at a distance of x = 3/2 m from point O.

Next, we can find the magnitude of the equivalent force by taking the integral of the loading over the length of the loading and setting it equal to F:

F_equiv = integral of 200 N/m dx from x=0 to x=3

       = 200*x |_0^3

       = 600 N

Finally, we need to find the direction and magnitude of the equivalent couple moment. Since the force is vertical, the couple moment must be perpendicular to the plane of the diagram.  so the equivalent couple moment will be:

M_equiv = F_equiv * x

       = 600 N * 3/2 m

       = 900 Nm

Therefore, the equivalent force is 600 N and the equivalent couple moment is 900 Nm, both acting at a distance of x = 3/2 m from point O.

The overall transfer function for the two systems in series is 2/ s²(2s + 1)(3s + 1).

It should be noted that to develop the transfer function for the two systems in series, we need to first express them in terms of transfer functions:

For the first system:

2dy/dt + y = 1

2sY(s) + Y(s) = 1/s

Y(s)(2s + 1) = 1/s

Y(s) = 1/s(2s + 1)

For the second system:

3dy/dt + y = 2

3sY(s) + Y(s) = 2/s

Y(s)(3s + 1) = 2/s

Y(s) = 2/s(3s + 1)

The overall transfer function for the two systems in series is obtained by multiplying their individual transfer functions, since the output of the first system is the input to the second system.

Hence, the overall transfer function is given by:

G(s) = Y(s)/X(s) = (1/s(2s + 1)) * (2/s(3s + 1))

G(s) = 2/ s²(2s + 1)(3s + 1)

A controller system is a type of feedback system used to regulate the performance of an output device by comparing the output to a desired set point. It uses the difference between the two values (error) to continuously adjust a control input to reduce the error. In simple terms, the controller system monitors, adjusts, and regulates the operations of the output device to achieve a desired result. Common examples of controllers include thermostats, cruise control systems, and PID controllers.

(a) Controller PB setting when remote sensors with spans of 50°F, 150°F, and 200°F are used:
