Air enters a diffuser operating at steady state at 645°r, 15 lbf/in^2 with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. the ratio of the exit area to the inlet area is 8 assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °r, and pressure, in lbf/in^2, at the exit.
