500 kg/hr of steam drives turbine. the steam enters the turbine at 44 atm and 450 c at a velocity of 60 m/sec and leavects at point 5 m below the turbine inlet at atmospheric pressure and velocity of 360 m/sec. the turbine drives shaft work at a rate of 70 kw, and heat loss from the turbine is estimated to be 11.6 kw.
Calculate the specific enthalpy change associated with the process?
