Well Loss for Total Drawdown Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Well loss - (Measured in Meter) - Well loss is defined as the head loss in well.
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.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown: 5.1 Meter --> 5.1 Meter No Conversion Required
Change in Drawdown: 0.1 Meter --> 0.1 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CQⁿ = s_t-s --> 5.1-0.1

Evaluating ... ...

CQⁿ = 5

STEP 3: Convert Result to Output's Unit

5 Meter --> No Conversion Required

FINAL ANSWER

5 Meter <-- Well loss

What is Well Loss?

When water is pumped out of a well, the total drawdown caused includes not only that of the logarithmic drawdown curve at the well face, but also drawdown caused by flow through well screen and axial movement within the well. The latter drawdown is called well loss

How to Calculate Well Loss for Total Drawdown?

Well Loss for Total Drawdown calculator uses Well loss = Total Drawdown-Change in Drawdown to calculate the Well loss, The Well Loss for Total Drawdown is the drawdown caused by flow through well screen and axial movement within the well. Well loss is denoted by CQⁿ symbol.

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