The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. Air enters a set of these nozzles at 300 psia and 700°F with a velocity of 76 ft/s and exits at 250 psia and 645°F. Calculate the velocity at the exit of the nozzles. The specific heat of air at the average temperature of 672.5°F is cp=0.253 Btu/lbm⋅R .
The velocity at the exit of the nozzles is __________ ft/s.

Air at 80 kPa and 127°C enters an adiabatic diffuser steadily at a rate of 6600 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 400 K is h1 = 400.98 kJ/kg.
Determine the exit area of the diffuser.
The exit area of the diffuser is_______ m2.
