What does fluid statics study?
A
Fluids in motion B
Fluids at rest C
Gas laws D
Thermal conductivity
Analysis & Theory
Fluid statics deals with fluids that are not moving.
What is the formula for pressure at a depth h?
A
P = mgh B
P = ρgh C
P = Vgh D
P = h/g
Analysis & Theory
Pressure at depth = ρgh.
Which law states that pressure is transmitted equally in all directions?
A
Boyle’s Law B
Archimedes’ Law C
Pascal’s Law D
Newton’s Law
Analysis & Theory
Pascal’s Law describes pressure transmission in fluids.
What is buoyant force equal to?
A
Weight of object B
Volume of object C
Weight of fluid displaced D
Mass of fluid
Analysis & Theory
Buoyant force is equal to the weight of fluid displaced (Archimedes’ Principle).
If an object floats, what can be said about its weight and buoyant force?
A
Weight > Buoyant Force B
Weight < Buoyant Force C
Weight = Buoyant Force D
Weight = 0
Analysis & Theory
For an object to float, its weight must equal the buoyant force.
Which device is used to measure pressure in a fluid?
A
Thermometer B
Voltmeter C
Manometer D
Barometer
Analysis & Theory
A manometer uses liquid columns to measure pressure differences.
