Q1: (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: 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; The Rankine efficiency; (i) (v) (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 (a) for a steam supply condition of 40 bar and 350 °C and the same condenser pressure of 0.035 bar.

Question

Q1: (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: The work output neglecting the feed-pump work; (ii) (i) The work required for the feed pump: The heat transferred to the condenser cooling water, and the (111) 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; The Rankine efficiency; (v) (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 (a) for a steam supply condition of 40 bar and 350 °C and the same condenser pressure of 0.035 bar.
