Steam enters an adiabatic turbine operating at steady state with an enthalpy of $3251.0 \mathrm{~kJ} / \mathrm{kg}$ and leaves as a saturated mixture at $15 \mathrm{kPa}$ with quality (dryness fraction) $0.9 .$ The enthalpies of the saturated liquid and vapor at $15 \mathrm{kPa}$ are $h_{f}=225.94 \mathrm{~kJ} / \mathrm{kg}$ and $h_{g}=2598.3 \mathrm{~kJ} / \mathrm{kg}$ respectively. The mass flow rate of steam is $10 \mathrm{~kg} / \mathrm{s}$. Kinetic and potential energy changes are negligible. The power output of the turbine in $M W$ is
(A) 6.5
(B) 8.9
(C) 9.1
(D) 27.0
