Q_e = 2.7*T*Δs
This formula uses 3 Variables

Variables Used

First Estimate of the Pumping Rate - (Measured in Cubic Meter per Second) - The First Estimate of the Pumping Rate refers to the preliminary calculation used to determine the amount of water that can be pumped from a well.
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.
Drawdown Across One Log Cycle - The Drawdown Across One Log Cycle is referred as change in water level (or hydraulic head) in an aquifer due to pumping from a well.

STEP 1: Convert Input(s) to Base Unit

Transmissivity: 11 Square Meter per Second --> 11 Square Meter per Second No Conversion Required
Drawdown Across One Log Cycle: 44.55 --> No Conversion Required
