5.4 At steady state, a power cycle having a thermal efficiency of 38% generates 100MW of electricity while discharging energy by heat transfer to cooling water at an average temperature of 21C. The average temperature of the steam passing through the boiler is 482C. Determine (a) the rate at which energy is discharged to the cooling water, in MW. (b) the minimum theoretical rate at which energy could be discharged to the cooling water, in MW. Compare with the actual rate and discuss
