Change in Drawdown given Formation Constant T Solution

Follow our step by step solution on how to calculate Change in Drawdown given Formation Constant T?

FIRST Step Consider the formula

Δd = \frac{2.303 \cdot Q}{4 \cdot π \cdot F c}

Next Step Substitute values of Variables

∴

Δd = \frac{2.303 \cdot 1.01m³/s}{4 \cdot π \cdot 0.8m²/s}

Next Step Substitute values of Constants

∴

Δd = \frac{2.303 \cdot 1.01m³/s}{4 \cdot 3.1416 \cdot 0.8m²/s}

Next Step Prepare to Evaluate

∴

Δd = \frac{2.303 \cdot 1.01}{4 \cdot 3.1416 \cdot 0.8}

Next Step Evaluate

∴

Δd = 0.231374482675026m

LAST Step Rounding Answer

∴

Δd = 0.2314m
