Heat Transfer Coefficient with Tube Loading for Condensation Outside Horizontal Tubes Solution

Follow our step by step solution on how to calculate Heat Transfer Coefficient with Tube Loading for Condensation Outside Horizontal Tubes?

FIRST Step Consider the formula

h average = 0.95 \cdot k f \cdot ({(ρ f \cdot (ρ f - ρ V) \cdot \frac{[g]}{μ \cdot Γ h})}^{\frac{1}{3}}) \cdot ({N Vertical}^{- \frac{1}{6}})

Next Step Substitute values of Variables

∴

h average = 0.95 \cdot 3.4W/(m*K) \cdot ({(995kg/m³ \cdot (995kg/m³ - 1.712kg/m³) \cdot \frac{[g]}{1.005Pa*s \cdot 0.0077})}^{\frac{1}{3}}) \cdot (270^{- \frac{1}{6}})

Next Step Substitute values of Constants

∴

h average = 0.95 \cdot 3.4W/(m*K) \cdot ({(995kg/m³ \cdot (995kg/m³ - 1.712kg/m³) \cdot \frac{9.8066m/s²}{1.005Pa*s \cdot 0.0077})}^{\frac{1}{3}}) \cdot (270^{- \frac{1}{6}})

Next Step Prepare to Evaluate

∴

h average = 0.95 \cdot 3.4 \cdot ({(995 \cdot (995 - 1.712) \cdot \frac{9.8066}{1.005 \cdot 0.0077})}^{\frac{1}{3}}) \cdot (270^{- \frac{1}{6}})

Next Step Evaluate

∴

h average = 1370.39226548401W/m²*K

LAST Step Rounding Answer

∴

h average = 1370.3923W/m²*K
