the work output neglecting the feed-pump work; (ii) the work required for the feed pump: (iii) the heat transferred to the condenser cooling water, and the amount of cooling water required through the condenser if the temperature rise of the water is assumed to be 5.5 K; (iv) the heat supplied; (v) the Rankine efficiency; (vi) the specific steam consumption.
(a) Steam is supplied, dry saturated at 40 bar to a turbine and the condenser pressure is 0.035 bar. If the plant operates on the Rankine cycle, calculate, per kilogram of steam:
(i) the work output neglecting the feed-pump work;
(ii) the work required for the feed pump:
(iii) the heat transferred to the condenser cooling water, and the amount of cooling water required through the condenser if the temperature rise of the water is assumed to be 5.5 K;
(iv) the heat supplied;
(v) the Rankine efficiency;
(vi) the specific steam consumption.
(b) For the same steam conditions calculate the efficiency and the specific steam consumption for a Carnot cycle operating with wet steam.
(C) Repeat Problem (a) for a steam supply condition of 40 bar and 350 °C and the same condenser pressure of 0.035 bar.
