Question 1.
What is the Mach number threshold for considering a flow as incompressible?
Show hintHide hint
Think about the relationship between flow speed and sound speed.
Question 2.
Define volumetric flow rate.
Show hintHide hint
Remember how area and velocity relate in fluid flow.
3Question 3.
What Mach number indicates incompressible flow?
- 0.5
- 0.3
- 0.1
Show hintHide hint
Recall the upper threshold for incompressibility.
4Question 4.
Is the assumption of incompressible flow always valid?
- Yes
- No
Show hintHide hint
Consider what differentiates compressible and incompressible flows.
Question 5.
A tank has a circular cross-section with a diameter of 1 meter and water flows in at a rate of 0.15 m³/s. What is the average velocity of water in the tank?
Show hintHide hint
Ensure to use the cross-sectional area formula for a circle in your calculations.
Question 6.
Given incompressible flow through varying pipe diameters, what steps would you take to analyze changes in flow velocity?
Show hintHide hint
Remember, density cancels out when dealing with incompressible fluids.
