Power (in kW) available at the nozzle of Pelton wheel turbine is calculated by
\(P= \dfrac{{ρ gQH}}{{1000}}\)
where ρ = Density of water, Q = Discharge through nozzle, H = Net Head on the Pelton wheel
Calculation:
Given:
Discharge through nozzle Q = 0.1 m3/s , net Head on the Pelton wheel H = 600 m, density of water ρ = 1000 kg/m3
\(P = \dfrac{{ρ gQH}}{{1000}} =\dfrac{1000\times10\times 0.1\times600}{1000}= 600\;kW\)
∴ The power available at the nozzle is 600 kW.
