Question

A pelton wheel has to develop 13230 kw under a net head of 800m while running at a speed of 600rpm. If the coeffient of the jet is cv=0.97, speed ratio=0.46 and the ratio of jet to wheel diameter is 1/16 , then the number of jets required by the pelton wheel is?

Answer 1

Answer:

The answer for the number of jests required by the pelton wheel is 2

Step-by-step explanation:

Brief explanation is presented in the following image.

I hope this may help you.

Answer 2

Step-by-step explanation:

first calculate runner velocity (u)

then calculate jet velocity at inlet (v1)

calculate wheel dia (D)

Calculate total discharge Q

then no of jets by calculating discharge per jet q

hope u will get clear idea about the solution
