Quiz 2

Question 1

What is mass flow rate equation?

Answer 1

mdot=densityAreaVelocity or Area*Velocity/specific volume

Question 2

What is conservation of mass flow rate?

Answer 2

Mass flow rate = sum of mass flow rates at inlets - sum of mass flow rates at outlets

Question 3

What is true about the mass flow rate of a control volume?

Answer 3

Mass flow rate in = mass flow rate out

Question 4

What is flow work?

Answer 4

mpv
m: mass flow rate
p: pressure
v: specific volume
All terms are either inlet or outlet

Question 5

What is energy flow rate by mass?

Answer 5

Edotmass=mdot(pressure*specific volume+Velocity^2/2)
