The enthalpy of the fluid ontering a rartion turbine is 1,000 btu per lb, this system changs in kinetie and pot? ntial enerxies are negligible and the system is essentially adiabatie? how can this problem be solved, sinee you do not know the sequence of processcs or the mechanism within the turbine?

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
