Transmissivity Absorptivity product Solution

Follow our step by step solution on how to calculate Transmissivity Absorptivity product?

FIRST Step Consider the formula

τα = τ \cdot \frac{α}{1 - (1 - α) \cdot ρ d}

Next Step Substitute values of Variables

∴

τα = 0.25 \cdot \frac{0.65}{1 - (1 - 0.65) \cdot 0.2}

Next Step Prepare to Evaluate

∴

τα = 0.25 \cdot \frac{0.65}{1 - (1 - 0.65) \cdot 0.2}

Next Step Evaluate

∴

τα = 0.174731182795699

LAST Step Rounding Answer

∴

τα = 0.1747
