5 cards from this section. Quick, good the night before a test.
Define incompressible flow.
Think of scenarios where density does not change.
What is the Mach number condition for flow to be considered incompressible?
Consider how speed relates to the speed of sound.
What Mach number indicates that a flow can be considered incompressible?
Remember the threshold for compressibility.
True or False: Incompressible flow means the flow's density can change significantly.
Think about the definition of incompressibility.
A tank with a diameter of 2 m is being filled with water at a rate of 0.1 m³/s. Calculate how high the water level rises in the tank after 10 seconds.
Remember how to convert the volume into height using the tank's area.
For a 0.5 m channel width carrying water at an average velocity of 2 m/s, calculate the flow rate. If the width increases to 1 m, what will the new flow rate be if the velocity remains the same?
Flow rate changes linearly with the area and velocity.
