4 cards from this section. Quick, good the night before a test.
What happens to shear stress in a fluid at rest?
Think about what it means for a fluid to be stationary.
Is pressure constant across horizontal surfaces in a fluid at rest?
Refer to the concept of hydrostatic equilibrium.
What is the pressure variation with depth in a fluid?
Refer back to the hydrostatic pressure equation.
True or False: Gauge pressure is measured relative to absolute zero pressure (vacuum).
Think about the reference point for gauge pressure.
A fluid column of height 10 m is in equilibrium. If the density of the fluid is 800 kg/m³, calculate the pressure at the base of the column.
Utilize the hydrostatic pressure formula.
Consider a scenario where a tank filled with a fluid at a density of 1200 kg/m³ has a hole on the side 5 m above the bottom. Calculate the pressure at the hole.
Remember that pressure depends on the height of the fluid column above the point of measurement.
