Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 \( \mathrm{MPa}, 500^{\circ} \mathrm{C} \), and \( 80 \mathrm{~m} / \mathrm{s} \), and the exit conditions are \( 30 \mathrm{kPa}, 92 \) percent quality, and \( 50 \mathrm{~m} / \mathrm{s} \). The mass flow rate of the steam is \( 12 \mathrm{~kg} / \mathrm{s} \). Determine \( (a) \) the change in kinetic energy, \( (b) \) the power output, and \( (c) \) the turbine inlet area.
