Kirpich equation for Time of Concentration Solution

Follow our step by step solution on how to calculate Kirpich equation for Time of Concentration?

FIRST Step Consider the formula

t c = 0.01947 \cdot (L^{0.77}) \cdot S^{- 0.385}

Next Step Substitute values of Variables

∴

t c = 0.01947 \cdot ({3km}^{0.77}) \cdot {0.003}^{- 0.385}

Next Step Convert Units

∴

t c = 0.01947 \cdot ({3000m}^{0.77}) \cdot {0.003}^{- 0.385}

Next Step Prepare to Evaluate

∴

t c = 0.01947 \cdot (3000^{0.77}) \cdot {0.003}^{- 0.385}

Next Step Evaluate

∴

t c = 86.7076936638551s

LAST Step Rounding Answer

∴

t c = 86.7077s
