The equation to determine number of buckets (vanes) in terms of runner diameter (D) and jet diameter (d) of the Pelton turbine is:

A. \(z = \left( {\frac{D}{{2d}}} \right) + 15\)
B. \(z = \left( {\frac{{2D}}{d}} \right) +15\)
C. \(z = \left( {\frac{D}{{2d}}} \right)\)
D. \(z = \left( {\frac{{3D}}{d}} \right) + 15\)
Answer» B. \(z = \left( {\frac{{2D}}{d}} \right) +15\)
