The Pressure Coefficient is the ratio of pressure forces to inertial forces.
The pressure coefficient is is the ratio of pressure forces to inertial forces and can be expressed as
Cp = dP / (ρ v2 / 2)
= dh (ρ v2 / 2 g) (1)
Cp = pressure coefficient
dp = pressure difference (N)
ρ = fluid density (kg/m3)
v = flow velocity (m/s)
dh = head (m)
g = acceleration of gravity (= 9.81 m/s2)
The pressure coefficient is important in most fluid flow applications.
The study of fluids - liquids and gases. Involving velocity, pressure, density and temperature as functions of space and time.
The Darcy-Weisbach equation can be used to calculate the major pressure and head loss due to friction in ducts, pipes or tubes.
Introduction to the Euler Number used in fluid mechanics.
