4 cards from this section. Quick, good the night before a test.
What is a control volume?
Think about what you would measure within a specified area.
What does the Reynolds Transport Theorem relate?
Consider mass and its movement.
What does the Reynolds Transport Theorem connect?
Consider what quantity is conserved in fluid mechanics.
True or False: The divergence of a velocity field being negative indicates a source.
Think about flow directions and sources versus sinks.
A pipe system experiences a mass inflow of 2 kg/s and outflow of 1.5 kg/s. Calculate the change in mass within a control volume over a time of 5 seconds.
Use the relationship of inflow and outflow in your calculation.
