Question

1. A simple Rankine cycle using water as the working fluid operates between the pressure limits of
7.5 kPa and 17.0 MPa and steam is superheated to 550 o C. Determine the: a) heat added per
cycle, b) heat rejected, c) cycle net work and d) the cycle thermal efficiency.
2. A boiler produces a steam at 2.417 Mpa and 468.9 o C. The steam enters a turbine where after
the extraction of energy enters a steam condensing unit. The pressure inside the condenser is
maintained at 0.1578 MPa. If the system operates on a simple Rankine cycle, solve for: a) heat
added per cycle, b) heat rejected, c) cycle net work and d) the cycle thermal efficiency.
