In order to win a design contract for a power plant, a company
is soliciting ideas from its three design teams.
The power plant receives heat from a
underground hot spring and rejects the waste heat to the surrounding
air. The three teams are required to submit the schematic of their
design and report the efficiency of the power plant.
What is known:
- The temperature of water in the underground hot spring is 140 oC
- The temperature of the surrounding air is 30 oC
- The thermal efficiencies reported by the three teams are:
Team A: 18.0%
Team B: 26.6%
Team C: 28.0%
