Air at 50 oC and 80 kPa enters the diffuser of a jet engine steadily with a velocity of 500 m/s. The inlet area of the diffuser is 0.4 m2. The air leaves the diffuser with a velocity that is very small compared to the inlet velocity. Determine the temperature (in oC) of the air leaving the diffuser.

Ok where is the image ?

The answer is letter c
