A Pelton wheel is to be designed for a pitch diameter of 1 m and jet diameter of 0.1 m. The number of buckets on the runner computed by Taygun's formula is:
Concept: Pelton wheel: It is a tangential flow impulse turbine in which the pressure energy of water is converted into kinetic energy to form a high-speed water jet and this jet strikes the wheel tangentially to make it rotate.
Taygun's formula: It is used to determine the number of buckets on the runner in the Pelton wheel turbine. It is given by the below formula:
Where D = Pitch or mean diameter, d = Nozzle or Jet diameter Calculation: Given, D = 1 m, d = 0.1 m The number of buckets on the runner by Taygun's formula 20
