Total Heat Transfer Coefficient Solution

Follow our step by step solution on how to calculate Total Heat Transfer Coefficient?

FIRST Step Consider the formula

h T = h FB \cdot ({(\frac{h FB}{h transfer})}^{\frac{1}{3}}) + h r

Next Step Substitute values of Variables

∴

h T = 921W/m²*K \cdot ({(\frac{921W/m²*K}{4.476W/m²*K})}^{\frac{1}{3}}) + 12.7W/m²*K

Next Step Prepare to Evaluate

∴

h T = 921 \cdot ({(\frac{921}{4.476})}^{\frac{1}{3}}) + 12.7

Next Step Evaluate

∴

h T = 5449.99397409331W/m²*K

LAST Step Rounding Answer

∴

h T = 5449.994W/m²*K
