Pressure Coefficient

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Pressure coefficient is a dimensionless number about the relative pressures throughout a flow field in fluid mechanics.

FORMULA

\(C_p = \frac { p \;-\; p_{\infty} }     {  \frac {1}{2} \rho_{\infty} v_{\infty}^2 } \;\)

Where:

\(C_p\) = pressure coefficient

\(p\) = pressure

\(p_{\infty}\) = free stream pressure

\(\rho _{\infty} \) = free stream density

\(v_{\infty}\) = free stream velocity
