Time at which Steady Shape Conditions Develop Solution

STEP 0: Pre-Calculation Summary
Formula Used
Time at Which Steady-shape Conditions Develop = (7200*Distance from Pumping Well^2*Storage Coefficient)/Transmissivity
tc = (7200*r^2*S)/τ
This formula uses 4 Variables
Variables Used
Time at Which Steady-shape Conditions Develop - (Measured in Second) - Time at which Steady-Shape Conditions develop at the Outermost Observation Well.
Distance from Pumping Well - (Measured in Meter) - Distance from Pumping Well to the point where drawdown occurs.
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.
Transmissivity - (Measured in Square Meter per Second) - Transmissivity describes the ability of the to transmit groundwater throughout its entire saturated thickness.
STEP 1: Convert Input(s) to Base Unit
Distance from Pumping Well: 3 Meter --> 3 Meter No Conversion Required
Storage Coefficient: 85 --> No Conversion Required
Transmissivity: 1.4 Square Meter per Second --> 1.4 Square Meter per Second No Conversion Required
