Question

When the flexibility of an outlet equals unity, then the outlet is said to be in?

(a) Sub-proportional

(b) Setting

(c) Sensitivity

(d) Proportionality

I had been asked this question during an interview for a job.

My question is from Regulation Modules topic in division Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Right choice is (d) Proportionality

The best explanation: An outlet is said to be proportional when the rate of change of outlet discharge equals the rate of change of channel discharge or in other words, we can say when flexibility equals unity then the outlet is proportional or in proportionality. Hence, F = (m/n) x (y/H) = 1.
