2 cards from this section. Quick, good the night before a test.
What is a control volume?
Think about areas where fluids are contained.
Define an extensive property.
Consider properties that increase with more substance.
What principle states that total momentum remains unchanged unless an external force acts?
Think of how forces interact with moving objects.
True or False: Extensive properties are independent of mass.
Consider how increasing the quantity changes these properties.
A fluid flows through a nozzle into a tank at a constant rate while the tank has an outflow spout. Create an equation using the Reynolds Transport Theorem to establish a relationship between influx and outflux in steady state.
Consider the conservation of mass as the first step in relating influx and outflux.
You have a closed tank filled with water, and water is removed at a constant rate while it's being replenished at a varying rate. Create a model to predict the water level over time using control volume concepts.
Express flows as functions of time if necessary.
