Coefficient of Permeability given Depth of Water in Two Wells Solution

Follow our step by step solution on how to calculate Coefficient of Permeability given Depth of Water in Two Wells?

FIRST Step Consider the formula

K w = \frac{Q}{\frac{2.72 \cdot b p \cdot (h 2 - h 1)}{\log ((\frac{r 2}{r 1}), 10)}}

Next Step Substitute values of Variables

∴

K w = \frac{1.01m³/s}{\frac{2.72 \cdot 2.36m \cdot (17.8644m - 17.85m)}{\log ((\frac{10m}{1.07m}), 10)}}

Next Step Prepare to Evaluate

∴

K w = \frac{1.01}{\frac{2.72 \cdot 2.36 \cdot (17.8644 - 17.85)}{\log ((\frac{10}{1.07}), 10)}}

Next Step Evaluate

∴

K w = 11.2572012205447m/s

Next Step Convert to Output's Unit

∴

K w = 1125.72012205447cm/s

LAST Step Rounding Answer

∴

K w = 1125.7201cm/s
