Draw a simple figure of Pelton Wheel Turbine Identifying its distinct features.
4 A Pelton Wheel operates in High head, Low flow condition. What will happen if you
use Pelton Wheel for low water head applications?
3 How was the required head for Pelton Wheel generated during the experiment?
44 Write down the Advantages and Disadvantages of Pelton Wheel over other types of
impulse turbine.
5 What is the function of a casing in a Pelton Wheel?
6+he rotational speed of a Pelton Wheel's Runner is 500 rpm, diameter of the runner is
2.5 m. The speed of water jet impinging on the buckets is 40 m/s. How much power
has been extracted from water? What would be your answer if you increase the water
jet speed around 3.27 times?
7+ Calculate the efficiency of the generator in this particular experiment for all the
observations you have taken. In order to get the maximum generator efficiency, at
what flowrate water should be supplied to the turbine?
