Constant Depression Head given Discharge and Time in Hours Solution

STEP 0: Pre-Calculation Summary

Formula Used

Constant Depression Head = Discharge/((2.303*Cross-Sectional Area*log((Depression Head 1/Depression Head 2),10))/Time)
H = Q/((2.303*A_cs*log((h₁/h₂),10))/t)
This formula uses 1 Functions, 6 Variables

Functions Used

log - Logarithmic function is an inverse function to exponentiation., log(Base, Number)

Variables Used

Constant Depression Head - Constant depression head in the well.
Discharge - (Measured in Cubic Meter per Second) - Discharge is the rate of flow of a liquid.
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.
Depression Head 1 - (Measured in Meter) - Depression Head 1 is the difference of level of waters table and the water level in the well when pumping stopped.
Depression Head 2 - (Measured in Meter) - Depression Head 2 is the difference of level of waters table and the water level in the well when pumping stopped.
Time - (Measured in Hour) - Time can be defined as the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future.

STEP 1: Convert Input(s) to Base Unit

Discharge: 1.01 Cubic Meter per Second --> 1.01 Cubic Meter per Second No Conversion Required
Cross-Sectional Area: 13 Square Meter --> 13 Square Meter No Conversion Required
Depression Head 1: 27 Meter --> 27 Meter No Conversion Required
Depression Head 2: 10 Meter --> 10 Meter No Conversion Required
Time: 4 Hour --> 4 Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = Q/((2.303*A_cs*log((h₁/h₂),10))/t) --> 1.01/((2.303*13*log((27/10),10))/4)

Evaluating ... ...

H = 0.05820867788511

STEP 3: Convert Result to Output's Unit

0.05820867788511 --> No Conversion Required

FINAL ANSWER

0.05820867788511 ≈ 0.058209 <-- Constant Depression Head

(Calculation completed in 00.007 seconds)

What is discharge ?

A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass.The units that are typically used to express discharge in streams or rivers include m³/s (cubic meters per second), ft³/s (cubic feet per second or cfs) and/or acre-feet per day.
