An adiabatic diffuser is employed to decrease the velocity of an airstream from 220 to 30 m/s. The air enters the diffuser at a rate of 8 kg/s with a temperature of 300c and a pressure of 100kpa. Determine the exit area of the diffuser if the exit pressure is 125kpa.(adsbygoogle = window.adsbygoogle || []).push({});

Answer is 0.37 m^2

Guys im really lost with this one.. I used equations pv=mrt, m=p'v'a, v=v'a

Note (v' is velocity as in> m/s and p' is density) just to prevent confusion

What i only got are the initial values v1, a1, p'1..
