Discharge from Open Well under Depression Head Solution

STEP 0: Pre-Calculation Summary

Formula Used

Yield from an Open Well = Specific Capacity*Area of the Well*Depression Head
Q_Y = K_s*A*H
This formula uses 4 Variables

Variables Used

Yield from an Open Well - (Measured in Cubic Meter per Second) - The Yield from an Open Well is referred as flow discharge into well under a depression head H.
Specific Capacity - The Specific Capacity is referred as amount of water furnished under a standard unit head.
Area of the Well - (Measured in Square Meter) - The Area of the Well is referred as land area around a well that is influenced by pumping.
Depression Head - (Measured in Meter) - The Depression Head is defined as height of the bottom of a well above the datum.

STEP 1: Convert Input(s) to Base Unit

Specific Capacity: 0.75 --> No Conversion Required
Area of the Well: 20 Square Meter --> 20 Square Meter No Conversion Required
Depression Head: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_Y = K_s*A*H --> 0.75*20*7

Evaluating ... ...

Q_Y = 105

STEP 3: Convert Result to Output's Unit

105 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

105 Cubic Meter per Second <-- Yield from an Open Well

(Calculation completed in 00.004 seconds)

What is Cone of Depression?

A Cone of Depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers (artesian), the cone of depression is a reduction in the pressure head surrounding the pumped well.
