The pressure and temperature of air change from (6.5000x10^0) bar to (2.000x10^0) bar and from (8.440x10^2) K to (6.260x10^2) K, respectively, in an air turbine operating under steady adiabatic conditions. Air flow rate through the turbine is (2.00x10^-1) kg/s. Determine the change in specific enthalpy of air as it flows through the turbine. Assume Cp = 1005 J/kg-K and R = 287 J/kg-K. Answer should be in J/kg with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible.
