Total Drawdown in Pumping Well Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Drawdown = Change in Drawdown+Well loss
s_t = s+CQⁿ
This formula uses 3 Variables

Variables Used

Total Drawdown - (Measured in Meter) - Total Drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test.
Change in Drawdown - (Measured in Meter) - Change in Drawdown in the Aquifer is a term applied to the maximum lowering of the groundwater table caused by pumping or artesian flow.
Well loss - (Measured in Meter) - Well loss is defined as the head loss in well.

STEP 1: Convert Input(s) to Base Unit

Change in Drawdown: 0.1 Meter --> 0.1 Meter No Conversion Required
Well loss: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s_t = s+CQⁿ --> 0.1+5

Evaluating ... ...

s_t = 5.1

STEP 3: Convert Result to Output's Unit

5.1 Meter --> No Conversion Required

FINAL ANSWER

5.1 Meter <-- Total Drawdown

Drawdown in aquifer caused by pumping at any point in aquifer

Go Possible Drawdown in Confined Aquifer = Pumping Rate*Time Period/(Transmissivity*Storage Coefficient*Distance from Pumping Well^2)

Total Drawdown in Pumping Well expressed given Factors related to Hydraulic Characteristics

Go Total Drawdown = Factors related to Hydraulic Characteristics*Pumping Rate+(Factors related to Characteristics of the Well*Pumping Rate^2)

Drawdown in aquifer for total drawdown

Go Change in Drawdown = Total Drawdown-Well loss

Total Drawdown in Pumping Well

Go Total Drawdown = Change in Drawdown+Well loss

Well Loss for Total Drawdown

Go Well loss = Total Drawdown-Change in Drawdown

Total Drawdown in Pumping Well Formula

Total Drawdown = Change in Drawdown+Well loss
s_t = s+CQⁿ

What is Pumping Well?

A Pumping Well is a well in which pumping is required to increase the formation pressure to allow the free production flow. It is the opposite of a naturally flowing well because in such type of a well an external device such as a reciprocating pump is used to force the liquid to move out of the well.

How to Calculate Total Drawdown in Pumping Well?

Total Drawdown in Pumping Well calculator uses Total Drawdown = Change in Drawdown+Well loss to calculate the Total Drawdown, The Total Drawdown in Pumping Well is a term applied to the maximum lowering of the groundwater table caused by pumping or artesian flow. Total Drawdown is denoted by s_t symbol.

How to calculate Total Drawdown in Pumping Well using this online calculator? To use this online calculator for Total Drawdown in Pumping Well, enter Change in Drawdown (s) & Well loss (CQⁿ) and hit the calculate button. Here is how the Total Drawdown in Pumping Well calculation can be explained with given input values -> 5.1 = 0.1+5.
