Question 1.
What is the condition for a flow to be considered incompressible?
Show hintHide hint
Think about the relationship between flow speed and sound.
Question 2.
Define volumetric flux.
Show hintHide hint
What two quantities are multiplied to get this?
3Question 3.
What Mach number indicates a flow can be considered incompressible?
- <0.1
- <0.3
- <0.5
Show hintHide hint
Refer to the definitions we discussed in class.
4Question 4.
True or False: Volumetric flux is affected by variations in density.
- True
- False
Show hintHide hint
Think about the assumptions we're making with incompressible flow.
Question 5.
In a cylindrical tank, the inflow is 50 liters/min and the outflow is 40 liters/min. Calculate the change in fluid storage over one hour.
Show hintHide hint
Remember to calculate how much is entering versus leaving.
Question 6.
Assuming a velocity profile across a pipe, how would you estimate the volumetric flow rate if the average velocity is 2 m/s and the pipe diameter is 0.1 m?
Show hintHide hint
Use J to calculate area based on diameter!
