Steam enters a diffuser at 240 degrees C and 70 kPa and exits at 320 degrees C and 150 kPa. The diameter at the entrance is 0.25 m and the diameter at the exit is .5 m. In this case, you cannot assume that the system is adiabatic. If the mass flow rate is 9.4 kg/s, find the rate of heat transfer to the surroundings.
