Nitrogen at 60 kPa and 7 deg C enters an adiabatic diffuser steadily with a velocity of 200 m/s and leaves at 85 kPa and 22 deg C. Determine (a) exit velocity (b) the ratio of inlet to exit area. Cp = 1.038 kJ/kgK
Added by Hailey C.
Step 1
At the inlet: Using the ideal gas law, we can find the specific volume of nitrogen at the inlet: v1 = R*T1/P1 = (8.314 kPa*m^3)/(kmol*K) * (7+273) K / 60 kPa = 0.0399 m^3/kg The specific enthalpy at the inlet can be found using the formula: h1 = Cp*T1 = 1.038 Show more…

Air at 80 kPa and 127°C enters an adiabatic diffuser steadily at a rate of 6000 kg/h and leaves at 100 kPa. The velocity of the airstream is decreased from 230 to 30 m/s as it passes through the diffuser. Find (a) the exit temperature of the air and (b) the exit area of the diffuser.
