IDEAL RANKINE
1) A basic, ideal Rankine cycle using water as the working fluid, has a saturated vapor exiting the steam
generator (boiler) at 12 MPa and saturated liquid exiting the condenser at 40 kPa. The mass flow rate of
the water through the cycle is 150 kg/s. Deterr
(a) the thermal efficiency, in %
(b) the rate of heat transfer, into the working fluid as it passes through the boiler, in MW,
(c) the rate of heat transfer, from the condensing steam as it passes through the condenser, in
MW
(d) the mass flow rate of the condenser cooling water, in kg/ h, if cooling water enters the
condenser at 12 C and exits at 37 C
