A) draw a simple process flow diagram for an ideal rankine power cycle and carefully explain each step in the cycle. (5 marks) b) with reference to the same cycle, draw the corresponding t/s diagram, explaining each step (5 marks) c) calculate the efficiency of the ideal rankine cycle drawn in (a) assuming that the boiler operates at 30 bar, the condenser operates at 0.04 bar and that the steam is superheated to 450 °c
