In an ideal rankine cycle (1-2-3-4-1 where 1 is turbine inlet, 2 is turbine exit) the following data are supplied: h1 = 3445, h2 = 2467, h3 = 340, and h4 = 344.
a) determine the back work ratio in percent (bwr is pumping power divided by turbine power) %
b) if the net power produced by the plant is 100 mw, determine the mass flow rate through the cycle. kg/s
c) the thermal efficiency of the cycle in percent.
