Description and Tags

The substances which can flow. This property applies to liquids and gases. We can't tell that solids can flow due to their high atomic forces of attraction.

11 Terms

1

Density

________ is a positive scalar quantity.

New cards
2

Density

Mass per unit volume of a substance is defined as density.

New cards
3

Buoyancy

If a body is fully or partially immersed in a fluid, it experiences an upward force due to the fluid called buoyant force, and the phenomenon is called buoyancy.

New cards
4

The Volume Flow Rate

It is the volume of fluid that passes through a particular point per unit of time.

f = Av

  • f = volumetric flow rate

  • A = cross-sectional area

  • v = flow velocity v

New cards
5

Bernoulli’s Effect

At comparable heights, the pressure is lower where the flow speed is greater.

New cards
6

Air Flow

The air on the bottom has greater pressure and pushes up on the wing giving the airplane lift force

New cards
7

Pressure

Pressure is defined as the magnitude of the normal force acting per unit surface area.

P = F/A

  • P is pressure

  • F is force

  • A is the area

New cards
8

Pressure units

  • Pascal (Pa) 1 Pa = 1 N/m^2

  • Practical units: atm, bar, torr

New cards
9

Hydrostatic pressure

It is the pressure due to the liquid.

New cards
10

Continuity equation

The density of the fluid is constant.

A1V1 = A2V2

  • A1 and A2 (cross-sectional areas)

  • V1 and V2 (flow velocities)

New cards
11

Bernoulli’s Equation (Conservation of energy in liquids)

  • fluid is incompressible.

  • fluid’s viscosity is negligible.

  • fluid is streamlined.

  • the equation is very similar to the conservation of energy with total mechanical energy.
