In a thermal powerplant operating on Rankine cycle, steam having enthalpy of 2995.1 kJ/kg and entropy 6.5422 kJ/kgK is fed to a turbine where it undergoes reversible adiabatic expansion to a pressure of 5000 N/m². If the data of steam at 5 kPa is tabulated below then calculate the specific steam consumption in kg/kW-h (neglecting pump work)

s_f = 0.4763 kJ/kgK, s_g = 8.3960 kJ/kgK, h_f = 139.23 kJ/kg, h_g = 2600 kJ/kg
