2 cards from this section. Quick, good the night before a test.
Define control volume in fluid mechanics.
Think about where you would analyze forces acting on fluids.
What is hydrostatic pressure?
Consider how pressure changes with depth in a fluid.
What stress acts perpendicular to the surface of a fluid?
Think about how these stresses are defined.
True or False: Gauge pressure is less than absolute pressure.
Consider the measurement reference points.
A fluid-filled tank has a height of 5 meters. Calculate the hydrostatic pressure at the bottom if the density of the fluid is 1000 kg/m³.
Use the hydrostatic pressure equation P = ρgz.
A barometer measures an atmospheric pressure of 101 kPa. If the liquid column is mercury, calculate the height of mercury in the barometer (density = 13,600 kg/m³).
Utilize the atmospheric pressure and density of mercury to find height.
