Specific Capacity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Specific Capacity = Pumping Rate/Drawdown Inside the Well
Ks = Q/st
This formula uses 3 Variables
Variables Used
Specific Capacity - Specific Capacity is the amount of water furnished under a standard unit head.
Pumping Rate - (Measured in Cubic Meter per Second) - Pumping Rate is the actual volumetric pumping rate.
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.
STEP 1: Convert Input(s) to Base Unit
Pumping Rate: 7 Cubic Meter per Second --> 7 Cubic Meter per Second No Conversion Required
Drawdown Inside the Well: 9 Meter --> 9 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ks = Q/st --> 7/9
Evaluating ... ...
Ks = 0.777777777777778
STEP 3: Convert Result to Output's Unit
0.777777777777778 --> No Conversion Required
FINAL ANSWER
0.777777777777778 0.777778 <-- Specific Capacity

6 Well Efficiency Calculators

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

Specific Capacity Formula

Specific Capacity = Pumping Rate/Drawdown Inside the Well
Ks = Q/st

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.

How to Calculate Specific Capacity?

Specific Capacity calculator uses Specific Capacity = Pumping Rate/Drawdown Inside the Well to calculate the Specific Capacity, The Specific Capacity is the amount of water furnished under a standard unit head which is a short-term sustainable discharge divided by the drawdown yielding the discharge. Specific Capacity is denoted by Ks symbol.

How to calculate Specific Capacity using this online calculator? To use this online calculator for Specific Capacity, enter Pumping Rate (Q) & Drawdown Inside the Well (st) and hit the calculate button. Here is how the Specific Capacity calculation can be explained with given input values -> 0.777778 = 7/9.

FAQ

What is Specific Capacity?
The Specific Capacity is the amount of water furnished under a standard unit head which is a short-term sustainable discharge divided by the drawdown yielding the discharge and is represented as Ks = Q/st or Specific Capacity = Pumping Rate/Drawdown Inside the Well. Pumping Rate is the actual volumetric pumping rate & Drawdown Inside the Well at the radius of the pumping well is a change in groundwater level due to an applied stress.
How to calculate Specific Capacity?
