A steam power plant operates on a simple ideal Rankine cycle between the pressure limits of $1\mathrm{.}4$ MPa and $50$ kPa. The temperature of the steam at the turbine inlet is $300\backslash$deg C$,$ and the mass flow rate of steam through the cycle is $35$ kg$/$s$.$ Show the cycle on a Ts diagram with respect to saturation lines, and determine $($i$)$ the thermal efficiency of the cycle and $($ii$)$ the net power output of the power plant,
