Kirpich Equation Solution

Follow our step by step solution on how to calculate Kirpich Equation?

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
