Air enters an insulated diffuser operating with steady flow and at steady state with a pressure of 0.7 bar, a temperature of 57 C, and a velocity of 200 m/s. At the exit, the pressure is 1 bar. The exit flow area is 20% greater than the inlet flow area. Potential energy effects can be neglected. Using the ideal gas model with a constant specific heat, Cp, evaluated at the inlet temperature, determine at the exit (a) the temperature, in K (b) the velocity, in m/s
