please solve without using any tables for enthalpy or heat capacity.

Q2: If you have an expansion device at which 60m/s steam enters at 723.15K and 44atm. If the steam leaves at 5m below the inlet level at atmospheric pressure with 6 times the inlet velocity. If the device produces 5104 watt of power while losses 1104kcal/hr. Determine specific enthalpy change in the system.
