Fluid Mechanics Formulas
Few important formulas related to fluid mechanics are:
Density
ρ = mV
Where:
- ρ is density of fluid
- m is mass, and
- v is volume
Pressure
P = F/A
Where:
- P is the pressure of the fluid,
- F is applied Force,
- A is area
Pressure at a Depth h in a Fluid of Constant Density
p = po + ρgh
where:
- p is pressure at height h
- po is the pressure at the fluid’s surface,
- ρ is the density of the fluid,
- g is the acceleration due to gravity, and
- h is the depth to which the object is submerged
Viscosity
η = FL/vA
Where:
- η is fluid viscosity
- F is force
- L is distance between the plates
- V is constant velocity
- A is area of the plate
Pascal’s Law
F = PA
Where:
- F is applied Force
- P is Pressure, and
- A is area under cross-section.
Reynolds Number (Re)
Re = pvL/μ
Where:
- ρ is the density of the fluid.
- v is the velocity of the fluid.
- L is a characteristic length (e.g., diameter of the pipe).
- μ is the dynamic viscosity of the fluid.
List of Physics Formulas
Physics is a fundamental branch of science that studies matter, its fundamental constituents, and its motion and behavior through space and time. Physics Formulas are very important during applications of various concepts of physics.
