Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept of Overall Efficiency:
The overall efficiency (ηoverall) of a station is the product of its thermal efficiency (ηthermal) and its electrical efficiency (ηelectrical).
The formula to calculate the overall efficiency is:
ηoverall = ηthermal × ηelectrical
Where,
- ηthermal = Thermal efficiency (in decimal form)
- ηelectrical = Electrical efficiency (in decimal form)
Given Data:
- Thermal efficiency (ηthermal) = 30% = 0.30
- Electrical efficiency (ηelectrical) = 95% = 0.95
Calculation:
Using the formula:
ηoverall = ηthermal × ηelectrical
Substituting the given values:
ηoverall = 0.30 × 0.95
ηoverall = 0.285
Converting to percentage:
ηoverall = 0.285 × 100%
ηoverall = 28.5%
Conclusion:
Hence, the overall efficiency of the station is 28.5%.
