Lag Time given Time of Peak Solution

Follow our step by step solution on how to calculate Lag Time given Time of Peak?

FIRST Step Consider the formula

t p = T p - \frac{t r}{2}

Next Step Substitute values of Variables

∴

t p = 7h - \frac{2h}{2}

Next Step Convert Units

∴

t p = 25200s - \frac{7200s}{2}

Next Step Prepare to Evaluate

∴

t p = 25200 - \frac{7200}{2}

Next Step Evaluate

∴

t p = 21600s

LAST Step Convert to Output's Unit

∴

t p = 6h

Go Time of Peak or Time of Rise

T p = (\frac{t r}{2}) + t p

Go Time of Recession as Suggested in SCS

Tc = 1.67 \cdot T p

Go Time of Peak given Time of Recession

T p = \frac{Tc}{1.67}

Go Peak Discharge

Q p = 2.08 \cdot \frac{A}{T p}
