Hi,
I want to calculate the pressure loss coefficent 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 lenght 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
