Well Loss given Drawdown Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss in Well = Total Drawdown-Aquifer Loss
CQⁿ = s_t-BQ
This formula uses 3 Variables

Variables Used

Head Loss in Well - (Measured in Meter) - The Head Loss in Well refers to the difference between the head of the aquifer immediately outside and in the well a head inside because of all these losses.
Total Drawdown - (Measured in Meter) - The Total Drawdown in Well refers to the reduction in water level from the original, static level to the level during pumping.
Aquifer Loss - (Measured in Meter) - The Aquifer Loss refers to the reduction in the volume of water stored in an aquifer.

STEP 1: Convert Input(s) to Base Unit

Total Drawdown: 28 Meter --> 28 Meter No Conversion Required
Aquifer Loss: 27.6 Meter --> 27.6 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CQⁿ = s_t-BQ --> 28-27.6

Evaluating ... ...

CQⁿ = 0.399999999999999

STEP 3: Convert Result to Output's Unit

0.399999999999999 Meter --> No Conversion Required

FINAL ANSWER

0.399999999999999 ≈ 0.4 Meter <-- Head Loss in Well

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 given Drawdown?

Well Loss given Drawdown calculator uses Head Loss in Well = Total Drawdown-Aquifer Loss to calculate the Head Loss in Well, Well Loss given Drawdown formula is defined as a measure of the head loss that occurs in the pump and the pipes connecting the pump to the well, which affects the overall performance of the well and the pump. It is an important parameter in evaluating the efficiency of a well system and predicting its behavior under different operating conditions. Head Loss in Well is denoted by CQⁿ symbol.

How to calculate Well Loss given Drawdown using this online calculator? To use this online calculator for Well Loss given Drawdown, enter Total Drawdown (s_t) & Aquifer Loss (BQ) and hit the calculate button. Here is how the Well Loss given Drawdown calculation can be explained with given input values -> 0.87 = 28-27.6.

FAQ

What is Well Loss given Drawdown?

Well Loss given Drawdown formula is defined as a measure of the head loss that occurs in the pump and the pipes connecting the pump to the well, which affects the overall performance of the well and the pump. It is an important parameter in evaluating the efficiency of a well system and predicting its behavior under different operating conditions and is represented as CQⁿ = s_t-BQ or Head Loss in Well = Total Drawdown-Aquifer Loss. The Total Drawdown in Well refers to the reduction in water level from the original, static level to the level during pumping & The Aquifer Loss refers to the reduction in the volume of water stored in an aquifer.

How to calculate Well Loss given Drawdown?

Well Loss given Drawdown formula is defined as a measure of the head loss that occurs in the pump and the pipes connecting the pump to the well, which affects the overall performance of the well and the pump. It is an important parameter in evaluating the efficiency of a well system and predicting its behavior under different operating conditions is calculated using Head Loss in Well = Total Drawdown-Aquifer Loss.
