Question
Superheated steam at a pressure of $10\text{ bar}$ and $400^\circ\text{C}$ is supplied to a steam engine. Adiabatic expansion takes place to release point at $0.9\text{ bar}$ and it exhausts into a condenser at $0.3\text{ bar}$. Neglecting clearance determine for a steam flow rate of $1.5\text{ kg/s}$ :
(i) Quality of steam at the end of expansion and the end of constant volume operation
(ii) Power developed
(iii) Specific steam consumption
(iv) Modified Rankine cycle efficiency.
