Question

Air enters a diffuser at a constant 109 Kpa , 60 celcius and 292 meters per second. The air exits at 305 Kpa , 10 Celcius and 10 meters per second. The area of the inlet is 104 cm^2. You can assume the air is an ideal gas. CP and CV values are assumed constant. Steady flow. There is no change in Potential Energy.

Ru=8.314 kj/kmol*k

Mair = 28.97 kg/kmol

cp=1.005 kj/kg*k

cv=0.718 kj/kg*k

Determine the average heat transfer time rate in kW.
