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

STEP 0: Pre-Calculation Summary

Formula Used

Total Drawdown = Factors related to Hydraulic Characteristics*Pumping Rate+(Factors related to Characteristics of the Well*Pumping Rate^2)
s_t = B*Q+(C*Q^2)
This formula uses 4 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.
Factors related to Hydraulic Characteristics - Factors related to Hydraulic Characteristics of the aquifer and the length of the pumping period.
Pumping Rate - (Measured in Cubic Meter per Second) - Pumping Rate is the actual volumetric pumping rate.
Factors related to Characteristics of the Well - Factors related to Characteristics of the Well.

STEP 1: Convert Input(s) to Base Unit

Factors related to Hydraulic Characteristics: 0.17 --> No Conversion Required
Pumping Rate: 7 Cubic Meter per Second --> 7 Cubic Meter per Second No Conversion Required
Factors related to Characteristics of the Well: 0.08 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s_t = B*Q+(C*Q^2) --> 0.17*7+(0.08*7^2)

Evaluating ... ...

s_t = 5.11

STEP 3: Convert Result to Output's Unit

5.11 Meter --> No Conversion Required

FINAL ANSWER

5.11 Meter <-- Total Drawdown

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 expressed given Factors related to Hydraulic Characteristics?

Total Drawdown in Pumping Well expressed given Factors related to Hydraulic Characteristics calculator uses Total Drawdown = Factors related to Hydraulic Characteristics*Pumping Rate+(Factors related to Characteristics of the Well*Pumping Rate^2) to calculate the Total Drawdown, The Total Drawdown in Pumping Well expressed given Factors related to Hydraulic Characteristics is measured as the difference between the initial level of water in a well before pumping, and the static, or stabilized, level of water after a long period of pumping. Total Drawdown is denoted by s_t symbol.
