Here is how the Length of fin equation looks like.

0.0312 = \frac{25 - (2 \cdot 12000)}{(4 \cdot 8)}

0.0312m = \frac{25m - (2 \cdot 12000mm)}{(4 \cdot 8)}

0.0312 = \frac{25 - (2 \cdot 12000)}{(4 \cdot 8)}

Length of fin Solution

Follow our step by step solution on how to calculate Length of fin?

FIRST Step Consider the formula

FL = \frac{P - (2 \cdot h c)}{(4 \cdot NF)}

Next Step Substitute values of Variables

∴

FL = \frac{25m - (2 \cdot 12000mm)}{(4 \cdot 8)}

Next Step Convert Units

∴

FL = \frac{25m - (2 \cdot 12m)}{(4 \cdot 8)}

Next Step Prepare to Evaluate

∴

FL = \frac{25 - (2 \cdot 12)}{(4 \cdot 8)}

Next Step Evaluate

∴

FL = 0.03125m

LAST Step Rounding Answer

∴

FL = 0.0312m
