Answer:
D
Explanation:
the way vertices are connected may be different so having same number of edges do not mean that total degree will also be same.

D. Perform a thorough visual inspection.
Answer:
a) 180 m³/s
b) 213.4 kg/s
Explanation:
= 1 m²
= 100 kPa
= 180 m/s
Flow rate

Volumetric flow rate = 180 m³/s
Mass flow rate

Mass flow rate = 213.4 kg/s
Answer:
Heat gain of 142 kJ
Explanation:
We can see that job done by compressing the He gas is negative, it means that the sign convention we are going to use is negative for all the work done by the gas and positive for all the job done to the gas. With that being said, the first law of thermodynamics equation will help us to solve this problem.
Δ
⇒
Δ

Therefore, the gas gained heat by an amount of 142 kJ.
