Who invented hydroelectricity?

In 1878, the world's first hydroelectric power scheme was developed at Cragside in Northumberland, England by William Armstrong. It was used to power a single arc lamp in his art gallery.

How to Calculate Hydro Power?

Hydro Power calculator uses Hydro Power=Water Density*9.81*Discharge*Head to calculate the Hydro Power, The Hydro Power is defined as that is the product of water discharge, head of water, density of water with constant g. Hydro Power and is denoted by P symbol.

How to calculate Hydro Power using this online calculator? To use this online calculator for Hydro Power, enter Water Density (WD), Discharge (Q) and Head (H) and hit the calculate button. Here is how the Hydro Power calculation can be explained with given input values -> 9.81 = 1*9.81*1*1.

FAQ

What is Hydro Power?
The Hydro Power is defined as that is the product of water discharge, head of water, density of water with constant g and is represented as P=WD*9.81*Q*H or Hydro Power=Water Density*9.81*Discharge*Head. Water Density is mass per unit of water, Discharge is the rate of flow of a liquid and Head is defined as the height of water columns.
How to calculate Hydro Power?
