Reversible Power Cycle

A proposed power cycle, consisting of strictly reversible processes, is to have a thermal efficiency of 30% while receiving heat from a hot reservoir and discharging heat to a nearby stream at 250C.

  1. Determine the minimum temperature of the hot reservoir.
  2. How much heat has to flow from the hot reservoir if the power produced is to be 120 kW.
  3. How much heat will be discharged into the stream ?
0oC = 273.15 oK
