T = (S*r_o^2)/(2.25*s_t)
This formula uses 4 Variables

Variables Used

Transmissivity - (Measured in Square Meter per Second) - Transmissivity is the rate at which groundwater flows horizontally through an aquifer or the degree to which a medium allows something, in particular electromagnetic radiation, to pass through it.
Storage Coefficient - Storage Coefficient is the volume of water released from storage per unit decline in hydraulic head in the aquifer, per unit area of the aquifer.
Distance from Pumping Well to Point Intersection - (Measured in Meter) - Distance from Pumping Well to Point Intersection where the straight line intersects the Zero-drawdown line.
Total Drawdown - (Measured in Meter) - Total Drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
