Follow our step by step solution on how to calculate Effective convection coefficient on outside given convection coefficient?

FIRST Step Consider the formula

h oe = \frac{h ia \cdot π \cdot d i \cdot h c}{(η \cdot A s) + AB}

Next Step Substitute values of Variables

∴

h oe = \frac{2W/m²*K \cdot π \cdot 35m \cdot 12000mm}{(0.54 \cdot 0.52m²) + 0.32m²}

Next Step Substitute values of Constants

∴

h oe = \frac{2W/m²*K \cdot 3.1416 \cdot 35m \cdot 12000mm}{(0.54 \cdot 0.52m²) + 0.32m²}

Next Step Convert Units

∴

h oe = \frac{2W/m²*K \cdot 3.1416 \cdot 35m \cdot 12m}{(0.54 \cdot 0.52m²) + 0.32m²}

Next Step Prepare to Evaluate

∴

h oe = \frac{2 \cdot 3.1416 \cdot 35 \cdot 12}{(0.54 \cdot 0.52) + 0.32}

Next Step Evaluate

∴

h oe = 4392.37321740251W/m²*K

LAST Step Rounding Answer

∴

h oe = 4392.3732W/m²*K
