Question

The discharge range of Gibb’s module varies from ____________

(a) 0.03 to 0.45 cumec

(b) 0.01 to 0.03 cumec

(c) 0.45 to 0.55 cumec

(d) 0.55 to 0.75 cumec

I have been asked this question in quiz.

My question comes from Types of Rigid Modules and Cattle Crossings topic in division Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

The correct option is (a) 0.03 to 0.45 cumec

To explain I would say: The discharge range of Gibb’s rigid module varies from 1 to 16 cusecs or 0.03 to 0.45 cumecs. It is often economical to construct it in R.C.C for lower values of discharge i.e. 1 to 3 cusecs. For discharge value greater than 3 cusecs it can be constructed in brick masonry.
