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

I'd like to ask this question from Classification of Hydro-Plant in section Hydro Electric Power Plant of Energy Engineering

Answer 1

Correct choice is (b) Medium head hydro-plant

Best explanation: If the water available is more than 30m but less than 100m, than this type of plant is known as medium head plant. Water stored in fore bay is conveyed to the turbine through penstocks. In these plants the river water is tapped off to a fore bay on one bank of rive.
