CEL expession for Cp in CFX-Pre

March 12, 2008, 13:12

Hi Cyclone

In order to find Cp we can also create an equation in following manner.

Cp = (Pressure-$pref [Pa])/(0.5*rho*u[m s^-1]^2)

Can you please explain what is difference between your expression and mine. I have used above equation (which is mentioned in one of the tutorials) to find my Cp but results are wrong. I dont quite understand why?

Regards kasim
