Depression Head in Well given Pumping Stopped and Constant Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depression Head = Depression Head in Well 2*exp((Constant*Time)/Cross Sectional Area)
h_d = h_w2*exp((K*t)/A_cs)
This formula uses 1 Functions, 5 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Depression Head - (Measured in Meter) - Depression Head is the difference of level of waters table and the water level in the well when pumping stopped.
Depression Head in Well 2 - (Measured in Meter) - Depression Head in Well 2 is depression head in the well at a time T after the pumping stopped.
Constant - Constant depending on the soil at the base of the well.
Time - (Measured in Hour) - Time refers to the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future.
Cross Sectional Area - (Measured in Square Meter) - Cross Sectional Area is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.

STEP 1: Convert Input(s) to Base Unit

Depression Head in Well 2: 10 Meter --> 10 Meter No Conversion Required
Constant: 5 --> No Conversion Required
Time: 4 Hour --> 4 Hour No Conversion Required
Cross Sectional Area: 20 Square Meter --> 20 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_d = h_w2*exp((K*t)/A_cs) --> 10*exp((5*4)/20)

Evaluating ... ...

h_d = 27.1828182845905

STEP 3: Convert Result to Output's Unit

27.1828182845905 Meter --> No Conversion Required

FINAL ANSWER

27.1828182845905 ≈ 27.18282 Meter <-- Depression Head

(Calculation completed in 00.004 seconds)

What is Specific Capacity?

Specific Capacity refers to the efficiency of a well in producing water. It is a measure of how much water (in volume) a well can yield per unit of drawdown (or drop in water level) over a specific period of time. The specific capacity is typically expressed in units such as gallons per minute per foot (gpm/ft) or liters per second per meter (L/s/m).
