Number of fins in length L Solution

Follow our step by step solution on how to calculate Number of fins in length L?

FIRST Step Consider the formula

NF = \frac{2 \cdot A s}{π \cdot (({FD}^{2}) - ({d o}^{2}))}

Next Step Substitute values of Variables

∴

NF = \frac{2 \cdot 0.52m²}{π \cdot (({0.3m}^{2}) - ({0.26m}^{2}))}

Next Step Substitute values of Constants

∴

NF = \frac{2 \cdot 0.52m²}{3.1416 \cdot (({0.3m}^{2}) - ({0.26m}^{2}))}

Next Step Prepare to Evaluate

∴

NF = \frac{2 \cdot 0.52}{3.1416 \cdot (({0.3}^{2}) - ({0.26}^{2}))}

Next Step Evaluate

∴

NF = 14.7786732871046

LAST Step Rounding Answer

∴

NF = 14.7787
