Problem Statement An ideal Rankine cycle operates with a steam generator pressure of 80 bar and a condenser pressure of 8 kPa. The exit of the condenser is a saturated liquid. The steam generator exit temperature is 580 °C and the mass flow rate is 70 kg/s. What is the quality at the turbine exit? Also, calculate the cycle efficiency, the back work ratio, and the net power produced.
