Step 5 - Test Your Repair.

Explanation:

Answer: Pat spent 12 more minutes playing baseball than soccer.

Explanation:

1 hour = 60 minutes

60 + 17 = 77

77 - 65 = 12

Answer:

a. The thermal efficiency of the actual cycle is 45%

ii) The rate at which energy is rejected by heat transfer to the cold reservoir  is 0.55 MW

b. The (maximum) cycle efficiency, is 50%

The rate of energy rejection to the cold reservoir by heat transfer is 0.55 MW

Therefore, there is an increased efficiency and reduced heat rejection in the reversible power cycle working between the given two reservoirs

Explanation:

The given parameters are;

The temperature of the hot reservoir, [tex]T_H[/tex] = 600 K

The temperature of the hot reservoir, [tex]T_C[/tex] = 300 K

The power output, [tex]\dot W[/tex] = 0.45 MW = The cycle work per second

The heat input from the hot reservoir, [tex]\dot Q_{in}[/tex] = 1 MW

a. The thermal efficiency of the actual cycle is given by the work done divided by the heat supplied as follows;

[tex]\eta_{actual} = \dfrac{\dot W}{\dot Q_{in}}[/tex]

Therefore, we have;

[tex]\eta_{actual} = \dfrac{0.45 \ MW}{1 \ MW} = 0.45 = 45 \%[/tex]

The thermal efficiency of the actual cycle, [tex]\eta_{actual}[/tex] = 45%

ii) The rate at which energy is rejected by heat transfer to the cold reservoir,  [tex]\dot Q_{c}[/tex], is given as follows;

[tex]\dot Q_{in}[/tex] = [tex]\dot Q_{c}[/tex] + [tex]\dot W[/tex]

∴ [tex]\dot Q_{c}[/tex]  = [tex]\dot Q_{in}[/tex] - [tex]\dot W[/tex]

Therefore, we have;

[tex]\dot Q_{c}[/tex]  = 1 MW - 0.45 MW = 0.55 MW

The rate at which energy is rejected by heat transfer to the cold reservoir,  [tex]\dot Q_{c}[/tex] = 0.55 MW

b. For a reversible power cycle, we have the maximum cycle efficiency, [tex]\eta_{maximum}[/tex], given as follows;

[tex]\eta_{maximum} = \dfrac{T_H - T_C}{T_H}[/tex]

[tex]\therefore \eta_{maximum} = \dfrac{600 \, K - 300 \, K}{600 \, K} = 0.5 = 50\%[/tex]

The maximum cycle efficiency, [tex]\eta_{maximum}[/tex] = 50%

The rate of work done by the cycle, [tex]\dot W[/tex], is therefore give as follows;

[tex]\eta_{maximum} = \dfrac{\dot W}{\dot Q_{in}}[/tex]

Therefore;

[tex]\dot Q_{in}[/tex] × [tex]\eta_{maximum}[/tex] = [tex]\dot W[/tex]

1 MW × 50% = 0.5 MW = [tex]\dot W[/tex]

[tex]\dot W[/tex] = 0.5 MW

[tex]\dot Q_{c}[/tex]  = [tex]\dot Q_{in}[/tex] - [tex]\dot W[/tex]

∴  [tex]\dot Q_{c}[/tex] = 1 MW - 0.5MW = 0.5MW

[tex]\dot Q_{c}[/tex] = 0.5MW

The rate of energy rejection to the cold reservoir by heat transfer, [tex]\dot Q_{c}[/tex] = 0.55 MW

Therefore the frequency and the rate at which energy is rejected by heat transfer to the cold reservoir are both higher for the reversible power cycle

Explanation:

Answer:

Either D or C

Both of these masks are used for dust, but since half masks are generally cheaper and easier to use, I'd go with C.

If this is correct, I'd appreciate a brainliest.

Answer:

Electromechanical systems or devices are systems or devices that involves the interaction between electrical systems and mechanical systems in which the motion of mechanical parts is converted to electrical energy or made to interact with energy or in which electrical energy is converted to mechanical energy or interacts with a moving mechanical system

Therefore;

Electromechanical systems convert electrical energy input into a mechanical energy output

Answer:

A good engineerer will look like this...

An engineer must know how the system works, what can go wrong and how to fix it. This requires an ability to think logically, and evaluate and understand each element that makes it up. Successful engineers are naturally curious and always looking for ways to make things better

Explanation:

Hope this helps!

Have a great day!
