WebThe power in a flow. The relevant calculation for the power contained in a flow through a rotor is: Power (in watts) = ( V^3 ) x 0.5 x p x A. V is the water flow speed in metres per second – this then needs to be cubed (raised to the power of 3). p is the density, which is about 1000 kg per cubic metre for water. Web27 Jul 2010 · What is river flow? Volumetric flow rate measures the speed at which a volume of water in a river is travelling downstream (often reported in cubic feet per second). When flow rate increases, water has a greater ability to erode its channel and banks. More and heavier sediment can be carried by the river, which increases the river’s turbidity.
Webmass flow rate in kg/s (numerically the same as the flow rate in litres/second because 1 litre of water weighs 1 kg) g the gravitational constant, which is 9.81m/s 2 H net the net head.
