How to Calculate Well Efficiency?
Well Efficiency calculator uses Well Efficiency=(Drawdown in the Aquifer/Drawdown Inside the Well)*100 to calculate the Well Efficiency, The Well Efficiency can be defined as the ratio of the drawdown in the aquifer at the radius of the pumping well to the drawdown inside the well . Well Efficiency and is denoted by E symbol.
How to calculate Well Efficiency using this online calculator? To use this online calculator for Well Efficiency, enter Drawdown in the Aquifer (s_{a}) and Drawdown Inside the Well (s_{t}) and hit the calculate button. Here is how the Well Efficiency calculation can be explained with given input values -> 50 = (0.01/0.02)*100.
