Question

A thermal power plant is running with no reheat or regeneration. The specific enthalpy and specific entropy of steam at the turbine inlet are 3344 kJ kg13344 \text{ kJ kg}^{-1} and 6.5 kJ kg1 K16.5 \text{ kJ kg}^{-1} \text{ K}^{-1}, respectively. The turbine isentropic efficiency is 0.90.9, and the mass flow rate of steam at the turbine inlet is 102 kg s1102 \text{ kg s}^{-1}. The turbine power output is _____________ MW (rounded off to 1 decimal place).
