How Can I Calculate the Pressure Loss Coefficient of a Diffuser?

frenchero · Jul 24, 2009

Hi,
I want to calculate the pressure loss coefficient for a diffuser but I can't find the equation. I tried with bernoulli but I don't get it. I've read that the coefficient depends on the length the scale and conical degree of the difuser?

Can you help me?

thank you!

hi,

Without the dimensions i can't calculate it properly, but 0.4 x 1/2pv^2 will more than cover the resistance in pascals.

p= air density which is approx 1.2 kg m^3
