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
t_c = (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) - The Transmissivity refers to the measure of how much water can be transmitted horizontally through an aquifer is the product of the hydraulic conductivity of the aquifer and its 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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_c = (7200*r^2*S)/τ --> (7200*3^2*85)/1.4

Evaluating ... ...

t_c = 3934285.71428571

STEP 3: Convert Result to Output's Unit

3934285.71428571 Second -->65571.4285714286 Minute (Check conversion here)

FINAL ANSWER

65571.4285714286 ≈ 65571.43 Minute <-- Time at Which Steady-shape Conditions Develop
