Concentration ratio of collector Solution

Follow our step by step solution on how to calculate Concentration ratio of collector?

FIRST Step Consider the formula

C = \frac{W - D o}{π \cdot D o}

Next Step Substitute values of Variables

∴

C = \frac{7m - 2m}{π \cdot 2m}

Next Step Substitute values of Constants

∴

C = \frac{7m - 2m}{3.1416 \cdot 2m}

Next Step Prepare to Evaluate

∴

C = \frac{7 - 2}{3.1416 \cdot 2}

Next Step Evaluate

∴

C = 0.795774715459477

LAST Step Rounding Answer

∴

C = 0.7958
