DESIGN OF A HIGH EFFICIENCY PELTON
TURBINE

2.  What is Pelton wheel ?
 an impulse turbine
 works under high head but
low discharge
 its main component is the
nozzle
 contains no. of buckets
 used to produce electrical
energy

5.  Calculations used for designing
Bucket Width b = 28.8 mm
Bucket Height h = 24.3 mm
Cavity Length h1 = 3.2 mm
Length to Impact Point h2 = 13.5 mm
Bucket Depth t = 8.1 mm
Cavity Width a = 10.8 mm
Offset of Bucket k = 6.8 mm
Pitch Circle Diameter D = 85 mm
Jet Diameter d = 4.5 mm
No. of buckets designed= 20
