Question

What's the meaning of a pressure coefficient in fluid mechanics?

Answer 1

Hello mate here is your answer.

The pressure coefficient is a dimensionless number which describes the relative pressuresthroughout a flow field in fluid dynamics. ... In many situations in aerodynamics and hydrodynamics, the pressure coefficient at a point near a body is independent of body size.

Hope it helps you.

Answer 2

C p = pressure coefficient. dp = pressure difference

(N) ρ = fluid density (kg/m 3)

v = flow velocity (m/s)

dh = head (m) g = acceleration of gravity (= 9.81 m/s 2)
