4 cards from this section. Quick, good the night before a test.
Define hydrostatic pressure.
Think about fluids and their weight.
What is the formula for calculating pressure in a fluid?
Consider fluid density, gravity, and height.
What is hydrostatic pressure calculated from?
Remember the equation P = ρgh.
True or False: Buoyancy is always equal to the weight of the submerged fluid.
Consider what happens when an object is placed in water.
A gate of height 1 meter has water exerting pressure on it at various depths. Calculate the total force acting on the gate and locate the position where this force acts.
Remember pressure is depth-dependent, calculate forces accordingly.
A manometer connected to a gas pipe shows a 150 mm rise with mercury of specific gravity 13.6. Calculate the pressure in the gas line.
Use the relationship between heights and pressure differences.
