If E1 is the energy before the hydraulic jump and E2 is the energy after the hydraulic jump the efficiency of jump is then given by _____________________?

Correct answer: D

Efficiency is defined as output divided by input. In a hydraulic jump, the specific energy before the jump (E1) acts as the input, and the specific energy after the jump (E2) is the useful output. Therefore, efficiency = E2 / E1.
