Fluid Mechanics Quiz

What is hydrostatics?

• Studies the behavior of fluids

• Study of fluids at rest

• Study of gas dynamics

• Study of thermal properties of fluid

Defined as the mass per unit volume of a substance.

• Density

• Specific Weight

• Viscosity

• Compressibility

A certain liquid has a density of 940 kg/m3, and the pressure at the bottom of a container filled with this liquid is 2500 Pa. What is the height (h) of the liquid in the container?

• 0.26 m

• 0.27 m

• 0.28 m

• 0.29 m

Which equation represents the fundamental principle of hydrostatics?

• P = FA

• P = ρgh

• F = ma

• v = d/t

Which of the following affects buoyancy?

• Shape of the object

• Density of the fluid

• Volume of displaced fluid

• All of the above

The simplest type of manometer, consisting of a vertical tube open at the top and connected to the point where the pressure is to be measured.

• Piezometer

• U-tube manometer

• Differential manometer

• Inclined manometer

What unit is pressure commonly measured in?

• Kilograms

• Newtons

• Pascals

• Meters

A water tank is filled to a height of 10 meters. The density of water (ρ) is approximately 1000 kg/m3. What is the pressure at the bottom of the tank?
