Question

What is the formula for discharge, when standing wave flume is used?

(a) Q = 1.7 x B x H^3/2

(b) Q = 1.7 x Cd x B x H^3/2

(c) Q = 1.7 x Cd x B x H

(d) Q = 1.7 x Cd x H^3/2

This question was addressed to me in my homework.

Enquiry is from Regulation Modules topic in section Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Right choice is (b) Q = 1.7 x Cd x B x H^3/2

Explanation: When the width of the throat (B) is known we can calculate the discharge in the standing wave flume using the formula, Q = 1.7 x Cd x B x H^3/2  where Cd = 0.95 to 1.
