Pressure Coefficient

The pressure coefficient is important in most fluid flow situations

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.
