WebThe height difference between the mill race and the tailrace is ten feet (3 meters), and the stream can supply, on average, 100 cubic feet of water per second (2.8 m^3 / sec). The planned turbine would be 66% efficient under those conditions. Power (watts) = density of water * height * flow rate * acceleration of gravity * coefficient of efficiency WebThe Gravity Flow Calculator is based on the equations and the example above above.

WebSolving for the velocity, we obtain v = 2 mg ρ CA. 5.19 Assume the density of air is ρ = 1. 21 kg /m 3. A 75-kg skydiver descending head first will have an area approximately A = 0. 18 m 2 and a drag coefficient of approximately C = 0. 70. We find that v = 2 ( 75 kg) ( 9 .80 m /s 2) ( 1. 21 kg /m 3) ( 0. 70) ( 0.18 m 2) = 98 m/s = 350 km/h. 5.20 WebThe height difference between the mill race and the tailrace is ten feet (3 meters), and the stream can supply, on average, 100 cubic feet of water per second (2.8 m^3 / sec). The planned turbine would be 73% efficient under those conditions. Power (watts) = density of water * height * flow rate * acceleration of gravity * coefficient of efficiency WebJun 21, 2024 · This equation only applies to water, and it calculates the velocity of the water by relating the geometric properties of the pipe and the slope of the energy line. The Hazen–Williams equation or pipe velocity equation is given by: \footnotesize v = k \cdot C \cdot R^ {0.63}\cdot S^ {0.54} v = k ⋅ C ⋅ R0.63 ⋅ S 0.54 where: jhu office of financial aid
