Pressure Coefficient
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)
where
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.
