Peak Discharge of D-h Unit Hydrograph given Lag Time Solution

Follow our step by step solution on how to calculate Peak Discharge of D-h Unit Hydrograph given Lag Time?

FIRST Step Consider the formula

Q pd = (A) \cdot {(\frac{1.56}{T p1})}^{\frac{1}{0.9}}

Next Step Substitute values of Variables

∴

Q pd = (3km²) \cdot {(\frac{1.56}{26.48h})}^{\frac{1}{0.9}}

Next Step Convert Units

∴

Q pd = (3E+6m²) \cdot {(\frac{1.56}{26.48h})}^{\frac{1}{0.9}}

Next Step Prepare to Evaluate

∴

Q pd = (3E+6) \cdot {(\frac{1.56}{26.48})}^{\frac{1}{0.9}}

Next Step Evaluate

∴

Q pd = 129028.058709578m³/s

LAST Step Rounding Answer

∴

Q pd = 129028.0587m³/s
