Pumping Rate from Distance Drawdown Graphs Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pumping Rate = Transmissivity*2*pi*Drawdown Across Log Cycle/2.3
q = T*2*pi*Δs_D/2.3
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Pumping Rate - (Measured in Cubic Meter per Second) - The Pumping Rate is referred as volume of water (or other fluid) that is pumped per unit of time. It’s typically measured in units like liters per second (L/s) or cubic meters per hour (m³/h).
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 Log Cycle - The Drawdown Across 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 Log Cycle: 0.233 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q = T*2*pi*Δs_D/2.3 --> 11*2*pi*0.233/2.3

Evaluating ... ...
