The value of Cp for compressible flow can be given as ___________(a) C

1.	The value of Cp for compressible flow can be given as ___________(a) Cp = P2-P1(b) Cp = 0(c) Cp = (P2-P1) /q(d) Cp = 0.5ρV1^2The question was asked at a job interview.This interesting question is from Pressure Coefficient topic in portion Inviscid & Incompressible Flow of Aerodynamics
Answer» The CORRECT choice is (d) Cp = 0.5ρV1^2 For explanation: The pressure is given in terms of COEFFICIENT rather than the pressure itself. P2-P1 is the pressure DIFFERENCE at two different POINTS in the flow field. ‘q’ is the DYNAMIC pressure which is given by 0.5ρV1^2 and Cp is the coefficient of pressure.
