Output power estimations using 2 different barrel sizes
Calculation using simple formula for POWERHorsepower = Torque (foot pounds) x 2 pi x rpm / 33000 which simplifies to:Horsepower = Torque x rpm / 5252.Finding TORQUE by calculating the water pressure on the paddle area using:-Paddle Area x Length x density of water x (Velcity of current2 / 2 x gravitational constant)And multiplying this by RADIUSModel 1:- 1.5 Metre Diameter HEB
Model 2:- 2 Metre Diameter HEB
