Combined Overall Efficiency of Screen Solution

Follow our step by step solution on how to calculate Combined Overall Efficiency of Screen?

FIRST Step Consider the formula

E = \frac{B \cdot D \cdot X D \cdot (1 - X B)}{F \cdot F \cdot X F \cdot (1 - X F)}

Next Step Substitute values of Variables

∴

E = \frac{8kg/s \cdot 10kg/s \cdot 0.3 \cdot (1 - 0.1)}{20kg/s \cdot 20kg/s \cdot 0.2 \cdot (1 - 0.2)}

Next Step Prepare to Evaluate

∴

E = \frac{8 \cdot 10 \cdot 0.3 \cdot (1 - 0.1)}{20 \cdot 20 \cdot 0.2 \cdot (1 - 0.2)}

LAST Step Evaluate

∴

E = 0.3375
