Transmission Factor Solution

Follow our step by step solution on how to calculate Transmission Factor?

FIRST Step Consider the formula

τ = \frac{L t}{L i}

Next Step Substitute values of Variables

∴

τ = \frac{32.5lm}{7.7lm}

Next Step Prepare to Evaluate

∴

τ = \frac{32.5}{7.7}

Next Step Evaluate

∴

τ = 4.22077922077922

LAST Step Rounding Answer

∴

τ = 4.2208
