Drawdown given Specific Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drawdown Inside the Well = Pumping Rate/Specific Capacity
s_t = Q/K_s
This formula uses 3 Variables

Variables Used

Drawdown Inside the Well - (Measured in Meter) - Drawdown Inside the Well at the radius of the pumping well is a change in groundwater level due to an applied stress.
Pumping Rate - (Measured in Cubic Meter per Second) - Pumping Rate is the actual volumetric pumping rate.
Specific Capacity - Specific Capacity is the amount of water furnished under a standard unit head.

STEP 1: Convert Input(s) to Base Unit

Pumping Rate: 7 Cubic Meter per Second --> 7 Cubic Meter per Second No Conversion Required
Specific Capacity: 0.75 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s_t = Q/K_s --> 7/0.75

Evaluating ... ...

s_t = 9.33333333333333

STEP 3: Convert Result to Output's Unit

9.33333333333333 Meter --> No Conversion Required

FINAL ANSWER

9.33333333333333 ≈ 9.333333 Meter <-- Drawdown Inside the Well

Well Efficiency

Go Well Efficiency = (Change in Drawdown/Drawdown Inside the Well)*100

Drawdown Inside well given well efficiency

Go Drawdown Inside the Well = Change in Drawdown/Well Efficiency

Drawdown in aquifer given well efficiency

Go Change in Drawdown = Well Efficiency*Drawdown Inside the Well

Pumping Rate given Specific Capacity

Go Pumping Rate = Specific Capacity*Drawdown Inside the Well

Drawdown given Specific Capacity

Go Drawdown Inside the Well = Pumping Rate/Specific Capacity

Specific Capacity

Go Specific Capacity = Pumping Rate/Drawdown Inside the Well

Drawdown given Specific Capacity Formula

Drawdown Inside the Well = Pumping Rate/Specific Capacity
s_t = Q/K_s

What is Specific Capacity?

Specific Capacity is the amount of water that is furnished under unit lowering of the surface of the water in a well by pumping.
