Pelton-Turbine calculations
| Parameter | Symbol/Relationship | Unit | Notes |
|---|---|---|---|
| Jetspeed | <x 12>v = \sqrt{2*g*H}</x> | m/s | Due to friction losses the jet will be 2-4% slower |
| Height/Head | <x 12>H</x> | m | |
| Earth Gravitation | <x 12>g</x> | m/s² | 9,81 m/s² |
| Turbine RPM | <x 12>RPMt = {v}/{2R}</x> | rad/s | Optimum RPM is about 2-10% lower |
| Jet-Turbine Radius | <x 12>R</x> | m | Center axis to cup center |
| Jet cross-section | <x 12>A = {Q}/{v}</x> | m² | adjusted by nozzle |
| Water volume | <x 12>Q</x> | m³/s | |
| Jet diameter | <x 12>d = \sqrt4a-pi</x> | m | |
| Cup height | <x 12>b \approx 2.4*p</x> | m | +/- 12% tolerance in construction |
