Question

For a hydropower plant working on 150 m head, the water is sandy and the load on the plant is highly variable. Which type of turbine will generally be recommended?

(a) Pelton Turbine

(b) Francis turbine

(c) Kaplan turbine

(d) Propeller turbine

I have been asked this question by my college professor while I was bunking the class.

Query is from Hydro Electric Power in division Hydro Electric Power of Irrigation Engineering

Answer 1

The correct answer is (a) Pelton Turbine

For explanation I would say: For variable loads (part loads) and sandy water, Pelton’s wheel is most suitable. These are preferred where the available water source has a relatively high head at low flow rates.
