The following tests may be performed to get an idea of the probable yield of the well: 1. Pumping Test: The water level is depressed to an amount equal to the safe working head for the subsoil. Then the water level is kept constant by making the pumping rate equal to the percolation into the […]

How to Calculate the Specific Capacity of a Well? | Ground Water
Article shared by :
The specific capacity (Q/sw) of a well is the discharge per unit drawdown in the well and is usually expressed in lpm/m. This is a measure of the effectiveness of a well. From Eqs. (4.78), (5.89) and (5.90). Which shows that the specific capacity of a well is not constant but decreases with the increase […]
How to Select Proper Pumping Set? | Wells | Geography
Article shared by :
The selection of a proper pumping set is important to ensure continued satisfactory yields from wells and the factors to be considered are: (i) Finished inside diameter and total depth of the well. (ii) Yield from the well, the desired pumping rate and hours of pumping per day. (iii) The lowest pumping water level (in […]
