The pressure and temperature of air change from (4.500x10^0) bar to (2.000x10^0) bar and from (7.2000x10^2) K to (5.26x10^2) K, respectively, in an air turbine operating under steady adiabatic conditions. Air flow rate through the turbine is (3.0000x10^-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- %3D K. Answer should be in J/kg with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Activate Windo Go to Settings to act Answer (?)
