Convection Coefficient based on Inside Area Solution

Follow our step by step solution on how to calculate Convection Coefficient based on Inside Area?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

h ia = \frac{((0.54 \cdot 0.52m²) + 0.32m²) \cdot 14W/m²*K}{π \cdot 35m \cdot 12000mm}

Next Step Substitute values of Constants

∴

h ia = \frac{((0.54 \cdot 0.52m²) + 0.32m²) \cdot 14W/m²*K}{3.1416 \cdot 35m \cdot 12000mm}

Next Step Convert Units

∴

h ia = \frac{((0.54 \cdot 0.52m²) + 0.32m²) \cdot 14W/m²*K}{3.1416 \cdot 35m \cdot 12m}

Next Step Prepare to Evaluate

∴

h ia = \frac{((0.54 \cdot 0.52) + 0.32) \cdot 14}{3.1416 \cdot 35 \cdot 12}

Next Step Evaluate

∴

h ia = 0.00637468598730738W/m²*K

LAST Step Rounding Answer

∴

h ia = 0.0064W/m²*K
