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. 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..
