Drawdown across one log cycle given first estimate of pumping rate Solution

STEP 0: Pre-Calculation Summary
Formula Used
Drawdown Across One Log Cycle = First Estimate of the Pumping Rate/(2.7*Transmissivity)
Δs = Qe/(2.7*T)
This formula uses 3 Variables
Variables Used
Drawdown Across One Log Cycle - Drawdown Across One Log Cycle from Time-drawdown graphs.
First Estimate of the Pumping Rate - (Measured in Cubic Meter per Second) - First Estimate of the Pumping Rate is the actual volumetric pumping rate.
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.
STEP 1: Convert Input(s) to Base Unit
First Estimate of the Pumping Rate: 1323 Cubic Meter per Second --> 1323 Cubic Meter per Second No Conversion Required
Transmissivity: 11 Square Meter per Second --> 11 Square Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Δs = Qe/(2.7*T) --> 1323/(2.7*11)
Evaluating ... ...

What is Drawdown?

Drawdown is a change in groundwater level due to an applied stress, caused by events such as: Pumping from a well. Pumping from a neighboring well. Intensive water taking from local area. Seasonal declines as recharge rates lower
