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.
