The pressure and temperature of air change from 5.0 bar to 1.0 bar and from 800K to 580K, respectively, in an air turbine operating under steady adiabatic conditions. Air flow rate through the turbine is 0.5 kg/s. Determine the change in specific enthalpy and specific entropy of air as it flows through the turbine. Assume Cp= 1000 J/kg-K and R = 287 J/kg-K.

Question

The pressure and temperature of air change from 5.0 bar to 1.0 bar and from 800K to 580K,
respectively, in an air turbine operating under steady adiabatic conditions. Air flow rate
through the turbine is 0.5 kg/s. Determine the change in specific enthalpy and specific
entropy of air as it flows through the turbine. Assume Cp= 1000 J/kg-K and R = 287 J/kg-K.
