2 cards from this section. Quick, good the night before a test.
Define volumetric discharge in basic terms.
Think about how flow rate relates to area and velocity.
What does the mass conservation equation state?
Consider a system where fluid is entering and exiting.
What does volumetric discharge represent?
Think about how fluids flow.
True or False: Inflow must equal outflow in an incompressible flow.
Remember the balance of fluid entering and exiting.
A pipe has a diameter of 0.1 m and carries water at a speed of 2 m/s. Calculate the volumetric flow rate and find the force exerted on a valve which stops the flow.
Consider how you relate momentum changes with forces acting at outlets.
A jet of water strikes a flat plate at a speed of 10 m/s and has a cross-sectional area of 0.01 m². Calculate the force exerted when it hits the plate.
Use the relationship between flow rate and forces acting.
