Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air at 80 kPa and 127°C enters an adiabatic diffuser steadily at a rate of 5400 kg/h and leaves at 100 kPa. The velocity of the airstream is decreased from 230 m/s to 30 m/s as it passes through the diffuser. The gas constant of air is 0.287 kPa·m3/kg·K. The enthalpy of air at the inlet temperature of...
