Modified Basin Lag for Effective Duration Solution

Follow our step by step solution on how to calculate Modified Basin Lag for Effective Duration?

FIRST Step Consider the formula

t' p = (21 \cdot \frac{t p}{22}) + (\frac{t R}{4})

Next Step Substitute values of Variables

∴

t' p = (21 \cdot \frac{6h}{22}) + (\frac{2h}{4})

Next Step Convert Units

∴

t' p = (21 \cdot \frac{21600s}{22}) + (\frac{7200s}{4})

Next Step Prepare to Evaluate

∴

t' p = (21 \cdot \frac{21600}{22}) + (\frac{7200}{4})

Next Step Evaluate

∴

t' p = 22418.1818181818s

Next Step Convert to Output's Unit

∴

t' p = 6.22727272727273h

LAST Step Rounding Answer

∴

t' p = 6.2273h
