Qt = k*HWater*N/B
This formula uses 5 Variables
Variables Used
Discharge from Dam - (Measured in Cubic Meter per Second) - Discharge from Dam is the volumetric flow rate of water that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material.
Coefficient of Permeability of Soil - (Measured in Meter per Second) - The Coefficient of Permeability of Soil describes how easily a liquid will move through the soil.
Head of Water - (Measured in Meter) - Head of Water is defined as the height of water columns.
Equipotential Lines - Equipotential Lines is defined as the number of lines with same potential drop.
Number of Beds - The Number of Beds is defined as the number of beds between each of the same potential drops.
STEP 1: Convert Input(s) to Base Unit
Coefficient of Permeability of Soil: 10 Centimeter per Second --> 0.1 Meter per Second (Check conversion here)
Head of Water: 2.3 Meter --> 2.3 Meter No Conversion Required
Equipotential Lines: 4 --> No Conversion Required
Number of Beds: 2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qt = k*HWater*N/B --> 0.1*2.3*4/2
Evaluating ... ...
Qt = 0.46
STEP 3: Convert Result to Output's Unit
0.46 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
0.46 Cubic Meter per Second <-- Discharge from Dam
(Calculation completed in 00.004 seconds)
