Distance between well when Interference among well is present Solution

Follow our step by step solution on how to calculate Distance between well when Interference among well is present?

FIRST Step Consider the formula

B = \frac{R^{2}}{\exp (\frac{2 \cdot π \cdot K \cdot b \cdot (H - h w)}{Q t}) \cdot r}

Next Step Substitute values of Variables

∴

B = \frac{{100m}^{2}}{\exp (\frac{2 \cdot π \cdot 0.105cm/s \cdot 15m \cdot (20m - 2.44m)}{12.26m³/s}) \cdot 2.94m}

Next Step Substitute values of Constants

∴

B = \frac{{100m}^{2}}{\exp (\frac{2 \cdot 3.1416 \cdot 0.105cm/s \cdot 15m \cdot (20m - 2.44m)}{12.26m³/s}) \cdot 2.94m}

Next Step Convert Units

∴

B = \frac{{100m}^{2}}{\exp (\frac{2 \cdot 3.1416 \cdot 0.001m/s \cdot 15m \cdot (20m - 2.44m)}{12.26m³/s}) \cdot 2.94m}

Next Step Prepare to Evaluate

∴

B = \frac{100^{2}}{\exp (\frac{2 \cdot 3.1416 \cdot 0.001 \cdot 15 \cdot (20 - 2.44)}{12.26}) \cdot 2.94}

Next Step Evaluate

∴

B = 2951.85812820202m

LAST Step Rounding Answer

∴

B = 2951.8581m
