Modified Drawdown in Well 1 Solution

Follow our step by step solution on how to calculate Modified Drawdown in Well 1?

FIRST Step Consider the formula

s1' = s 1 - (\frac{{(s 1)}^{2}}{2 \cdot H i})

Next Step Substitute values of Variables

∴

s1' = 2.15m - (\frac{{(2.15m)}^{2}}{2 \cdot 2.54m})

Next Step Prepare to Evaluate

∴

s1' = 2.15 - (\frac{{(2.15)}^{2}}{2 \cdot 2.54})

Next Step Evaluate

∴

s1' = 1.24005905511811m

LAST Step Rounding Answer

∴

s1' = 1.2401m
