The efficiency of energy conversion on the energy flow through a hydroelectric power is?
Attached Figure / Diagram
A
\(\frac{E1}{E2}\)
B
\(\frac{E3}{E2}\)
C
\(\frac{E2}{E1}\)+ E2
D
\(\frac{E2}{E3}\) + E1
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Efficiency = \(\frac{\text{useful energy output from machine}}{\text{energy input into machine}}\)
= \(\frac{E3}{E2}\)
