Gas enters an adiabatic turbine with enthalpy 3456 kJ/kg and velocity 100 m/s. It leaves the turbine with enthalpy 2675 kJ/kg and velocity 200 m/s. Had the flow been isentropic, the enthalpy would be 2315 k./kg at exit. Assume (V2s-V2). Determine the following: QUESTION 2 Total enthalpy at inlet in kJ/kg Enthalpy at exit in kJ/kg A 2392 B. 2695 C. 2461 D. 2335 Total isentropic enthalpy at exit in kJ/kg Total-to-total efficiency (%) The work done (in kJ/kg) E766...
