(b) Minimum Modular Head

(c) Efficiency of an Outlet

(d) Drowning Ratio

The question was asked during an interview.

Question is from Regulation Modules in portion Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Correct answer is (c) Efficiency of an Outlet

The explanation is: The ratio of head recovered (output) to the head put in (input) is known as efficiency of an outlet. If the head required for the operation that is head put in, is less more will be the efficiency. This efficiency is also a measure of conservation of head by the outlet.
