3 cards from this section. Quick, good the night before a test.
What is the condition for flow to be considered incompressible?
Think about the relation between flow speed and the speed of sound.
Write the formula for volumetric flow rate.
Recall what the terms represent in the context of fluid flow.
What is the relationship between Mach number and flow compressibility?
Remember how the flow speed compares to sound.
True or False: The density of an incompressible fluid remains constant under all conditions.
Think about the implications of the Mach number.
If a flume has two inlets with velocities of 0.2 m/s and 0.3 m/s, and a cross-section of 2 m², calculate the inflow. Then, if the outlet velocity is 0.4 m/s with a section of 1m², find the net loss.
Use Q = A * V to find both the inflow and outflow.
Given a seepage problem where velocity varies from 0.5 to 0.45 m/s through sections of identical area, calculate the change in seepage rate using the flow conservation principle.
Identify your inflow and outflow effectively.
