Formula Used

Transmissivity = First Estimate of the Pumping Rate/(2.7*Drawdown Across One Log Cycle)
T = Q_e/(2.7*Δs)
This formula uses 3 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.
First Estimate of the Pumping Rate - (Measured in Cubic Meter per Second) - First Estimate of the Pumping Rate is the actual volumetric pumping rate.
Drawdown Across One Log Cycle - Drawdown Across One Log Cycle from Time-drawdown graphs.

STEP 1: Convert Input(s) to Base Unit
