Question

I got this question by my college professor while I was bunking the class.

I'd like to ask this question from Tube Well-2 in division Ground Water for Irrigation through Wells and Tubewells of Irrigation Engineering

Answer 1

Right answer is (b) starting and stopping of pumping intermittently

The best I can explain: Rewhiding involves starting and stopping of pumping intermittently. It provides a relatively rapid change in the head of the well and can be done with any type of pump. However, the turbine pump installed with a foot valve is the most effective.
