Reversible Engine Calculation
Given:
- Heat received at 500K = 100 kJ
- Heat received at 400K = 40 kJ
- Heat rejected at 300K
Calculation
The work output of the engine can be calculated using the following formula:
W = QH - QC
where:
- W is the work output
- QH is the heat received
- QC is the heat rejected
First, we need to determine the amount of heat that is transferred to the engine:
Qin = Q1 + Q2 = 100 kJ + 40 kJ = 140 kJ
Next, we need to determine the efficiency of the engine:
e = 1 - TC/TH
where:
- e is the efficiency of the engine
- TC is the temperature of the cold reservoir
- TH is the temperature of the hot reservoir
Using the given temperatures, we can calculate the efficiency:
e = 1 - 300/500 = 0.4
Finally, we can calculate the work output:
W = e * Qin = 0.4 * 140 kJ = 56 kJ
Conclusion
The work output of the engine is 56 kJ.
