This question was posed to me in an online quiz.

I'm obligated to ask this question of Principal Components of a Hydro Electric Scheme in section Hydro Electric Power of Irrigation Engineering

Answer 1

Right answer is (b) surge chamber

The best explanation: The surge tank is mostly employed in a water power plant or in a large pumping plant to control the pressure variations resulting from rapid changes in the flow. It is done by admitting a large mass of water in the surge tank otherwise it would have flown out of the pipeline and returns to the tank due to closure of pipe end.
