Distance from observation well to real well Solution

Follow our step by step solution on how to calculate Distance from observation well to real well?

FIRST Step Consider the formula

r r = r i \cdot \sqrt{\frac{t r}{t i}}

Next Step Substitute values of Variables

∴

r r = 30m \cdot \sqrt{\frac{150min}{200min}}

Next Step Convert Units

∴

r r = 30m \cdot \sqrt{\frac{9000s}{12000s}}

Next Step Prepare to Evaluate

∴

r r = 30 \cdot \sqrt{\frac{9000}{12000}}

Next Step Evaluate

∴

r r = 25.9807621135332m

LAST Step Rounding Answer

∴

r r = 25.9808m
