Does air density increase as it passes through a diffuser?
My thermodynamics teacher has this question, and gave us answers, but the answer is as if the density stays the same as the entry density at the exit... but I have this feeling as if she did it wrong.
Pin = 300kPa, Tin = 290K, Pout = 1400kPa, Tout = 367.5K
In a diffuser there is a reduction in area. In terms of dynamic air compressors, the reduction in area is to convert velocity to pressure. To answer your question, I would venture to guess that the density would increase. But this is just a guess don't take it to the bank.
