Depression Head in Well at Time T after Pumping Stopped Solution

Follow our step by step solution on how to calculate Depression Head in Well at Time T after Pumping Stopped?

FIRST Step Consider the formula

h d = \frac{h1'}{\exp (K a \cdot t)}

Next Step Substitute values of Variables

∴

h d = \frac{20m}{\exp (2m/h \cdot 4h)}

Next Step Convert Units

∴

h d = \frac{20m}{\exp (0.0006m/s \cdot 4h)}

Next Step Prepare to Evaluate

∴

h d = \frac{20}{\exp (0.0006 \cdot 4)}

Next Step Evaluate

∴

h d = 19.9556049017121m

LAST Step Rounding Answer

∴

h d = 19.9556m
