Math Problem Statement
Solution
The problem is asking for the efficiency of two different engines. The efficiency is defined as:
Let's break it down:
a) Power generation station:
- Input power = 450,000 MW
- Output power = 95,000 MW
Using the formula:
b) Four-stroke diesel engine:
- Input power = 80 kW
- Output power = 22 kW
Using the formula:
I'll now calculate both efficiencies.The efficiencies for the two cases are:
a) Power generation station:
b) Four-stroke diesel engine:
