Overview

The pressure coefficient ( $C_p$ ) is a dimensionless number describing the relative pressure at a point in a flow field compared to the freestream dynamic pressure.

Variables

Symbol	Description	Unit
$C_p$	Pressure coefficient	—
$P$	Local pressure	Pa
$P_\infty$	Freestream pressure	Pa
$v_\infty$	Freestream velocity	m/s

Formula

$C_p = \frac{P - P_\infty}{\frac{1}{2}\rho v_\infty^2}$
