3 cards from this section. Quick, good the night before a test.
Define incompressible flow.
Think about the implications of high versus low Mach numbers.
What is the formula for volumetric flux?
How do area and velocity relate in a flow?
What is the effect on density in incompressible flow?
Remember the conditions under which we define incompressibility.
True or False: The Mach number is irrelevant for incompressible flow.
What does a Mach number below 0.3 imply?
A pipe has a varying diameter. If the velocity at the inlet is 3 m/s and the area is 0.2 m^2, determine the velocity at the outlet when the area is 0.1 m^2.
Think about how the area changes and how that affects velocity.
A tank with a constant inflow of 5 L/min is experiencing an outflow rate of 2 L/min. What is the rate of change of liquid height if the tank area is 0.5 m^2?
What does your mass balance tell you about the liquid level?
