Pressure Coefficient

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

Pressure Coefficient FORMULA

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

Where:

\(\large{ C_p }\) = pressure coefficient

\(\large{ p }\) = pressure

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

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

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