The pressure and temperature of air change from (5.5000x10^0) bar to (1.00x10^0) bar and from (7.900x10^2) K to (4.0600x10^2) K, respectively, in an air turbine operating under steady adiabatic conditions. Air flow rate through the turbine is (7.0000x10^-1) kg/s. Determine the change in specific entropy 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-K with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Ancwor
