4 cards from this section. Quick, good the night before a test.
What type of pressure is measured above atmospheric pressure?
Think about how pressure is measured in everyday devices like tire gauges.
What happens to shear stress when fluid is at rest?
Consider the forces acting on the fluid surfaces.
What is the primary force acting on a fluid at rest within a control volume?
Consider what forces are present when the fluid isn’t moving.
True or False: Gauge pressure can be negative.
Think about measuring pressure in a vacuum.
Calculate the absolute pressure at a depth of 10 meters of water. Given that the density of water is 1000 kg/m³ and atmospheric pressure is 101.3 kPa.
Remember to add atmospheric pressure to the hydrostatic pressure.
If the gauge pressure in a tire is 35 psi, what is the absolute pressure assuming atmospheric pressure is 14.7 psi?
Always add atmospheric pressure to get absolute pressure.
