Exit temperature of a diffuser calculator
WebThe diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor without any work or heat interactions. Calculate the velocity at the exit of a diffuser when air at 100 kPa and 30^\circ C 30∘C enters it with a velocity of 350 m/s and the exit state is 200 kPa and 90^\circ C. 90∘C. engineering. WebNov 12, 2014 · The calculation would be fairly simple: P_1*V_1 = P_2*V_2, rearrange to get P_1/P_2 = V_2/V_1. V_2/V_1 should be, if I am thinking correctly, the expansion ratio. P_1 would be the chamber pressure leaving us only to solve for P_2, which should be the pressure at the nozzle exit. I don't claim to be an expert in analyzing fluid flows, but this ...
