Question 1.
Define incompressible flow and its Mach number condition.
Show hintHide hint
Think about how Mach number relates to fluid velocity.
Question 2.
What is volumetric flux?
Show hintHide hint
Remember how it connects area and velocity!
3Question 3.
What Mach number indicates incompressible flow?
- Less than 0.3
- Greater than 0.3
- Equal to 1
Show hintHide hint
Recall the definition of incompressibility.
4Question 4.
True or False: In an incompressible flow, density variations are significant.
- True
- False
Show hintHide hint
Consider what the assumptions allow for.
Question 5.
A fluid flows through a pipe of radius R at a constant velocity V. Calculate the volumetric flow rate in terms of R and V.
Show hintHide hint
Recall the formula for the area of a circle.
Question 6.
If the Mach number increases to 0.4 in the same system, how does the analysis change?
Show hintHide hint
Consider what happens to properties of the fluid at higher speeds.
