What is an Aquifer?

Aquifer is rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone

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 (sa) and Drawdown Inside the Well (st) 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.

FAQ

What is 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 and is represented as E=(sa/st)*100 or Well Efficiency=(Drawdown in the Aquifer/Drawdown Inside the Well)*100. Drawdown in the Aquifer is a term applied to the maximum lowering of the groundwater table caused by pumping or artesian flow and Drawdown Inside the Well at the radius of the pumping well .
How to calculate 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 is calculated using Well Efficiency=(Drawdown in the Aquifer/Drawdown Inside the Well)*100.
