A stationary power plant produces \(1 \times 10^{7} \mathrm{~W}\) output when operating under the following conditions: Compressor inlet is \(0^{\circ} \mathrm{C}\) and \(1 \mathrm{bar}\) abs, turbine inlet is \(1250 \mathrm{~K}\), cycle pressure ratio is 10 , and fluid is air with negligible velocities. The turbine and compressor efficiencies are both \(90 \%\). Determine the cycle efficiency and the mass flow rate.
