Detention Time for Circular Tank Solution

Follow our step by step solution on how to calculate Detention Time for Circular Tank?

FIRST Step Consider the formula

T d = ({(D)}^{2}) \cdot (\frac{(0.011 \cdot D) + (0.785 \cdot d)}{Q d})

Next Step Substitute values of Variables

∴

T d = ({(4.8m)}^{2}) \cdot (\frac{(0.011 \cdot 4.8m) + (0.785 \cdot 3m)}{8.2m³/s})

Next Step Prepare to Evaluate

∴

T d = ({(4.8)}^{2}) \cdot (\frac{(0.011 \cdot 4.8) + (0.785 \cdot 3)}{8.2})

Next Step Evaluate

∴

T d = 6.76533073170732s

LAST Step Rounding Answer

∴

T d = 6.7653s
