The non-dimensional pressure coefficient (Cp) is a dimensionless number that describes the relative pressures throughout a fluid flow field. The pressure coefficient is used in aerodynamics and hydrodynamics to compare the pressure at different points in the flow with the freestream pressure and dynamic pressure.
- Non-dimensional pressure coefficient (Cp)
- Downstream (freestream) static pressure (p2) in N/m^2
- Upstream (freestream) static pressure (p1) in N/m^2
- Dynamic pressure (q1) in N/m^2
