Specific steam consumption.
PART C – (2 x 10 = 20 Marks)
1.Find the efficiency of the prime mover operating on the rankine cycle between 7bar for the following initial conditions.(a) The steam has a dryness fraction of 0.8(b) The steam is dry and saturated and(c) The steam is super heated to 350
o
C.Draw the T-S diagram for each case. Neglect the pump work.
2.
A reheat cycle works between 120bar and 0.035bar. The initial steamtemperature is 570
o
C. After isentropic expansion to dry saturated conditions, the steamis reheated to 500
