Question

At steady state, $500$ $\text{kg/s}$ of steam enters a turbine with specific enthalpy equal to $3500$ $\text{kJ/kg}$ and specific entropy equal to $6.5$ ${kJ \cdot kg^{-1} \cdot K^{-1}}$. 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 $2500$ $\text{kJ/kg}$ and $6.3$ ${kJ \cdot kg^{-1} \cdot K^{-1}}$, respectively, the work output from the turbine is ______________ $\text{MW}$ (in integer).
