Question

8.1 (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.
