At steady state, 500 kg/s of steam enters a turbine with specific enthalpy equal to 3500 kg and specific entropy equal to 6.5 kJ.kg⁻¹K⁻¹. It expands reversibly in the turbine to the condenser pressure. Heat loss occurs reversibly in the turbine at a temperature of 500 K. If the exit specific enthalpy and specific entropy are 2500 kJ/kg and 6.3 kJ.kg⁻¹K⁻¹, respectively the work output from the turbine is ___ MW (in integer)
