Time for Diffusion given Standard Deviation Solution

Follow our step by step solution on how to calculate Time for Diffusion given Standard Deviation?

FIRST Step Consider the formula

t D = \frac{{(σ)}^{2}}{2 \cdot D}

Next Step Substitute values of Variables

∴

t D = \frac{{(1.33)}^{2}}{2 \cdot 800m²/s}

Next Step Prepare to Evaluate

∴

t D = \frac{{(1.33)}^{2}}{2 \cdot 800}

Next Step Evaluate

∴

t D = 0.0011055625s

LAST Step Rounding Answer

∴

t D = 0.0011s
