Steam expands in a turbine from $4 \mathrm{MPa}$ and $500^{\circ} \mathrm{C}$ to $0.5 \mathrm{MPa}$ and $250^{\circ} \mathrm{C}$ at a rate of $1350 \mathrm{kg} / \mathrm{h}$. Heat is lost from the turbine at a rate of $25 \mathrm{kJ} / \mathrm{s}$ during the process. The power output of the turbine is $(a) 157 \mathrm{kW}$ (b) $207 \mathrm{kW}$ $(c) 182 \mathrm{kW}$ $(d) 287 \mathrm{kW}$ $(e) 246 \mathrm{kW}$
