Nusselt number for short pipes Solution

Follow our step by step solution on how to calculate Nusselt number for short pipes?

FIRST Step Consider the formula

Nu Avg = Nu \cdot (1 + (\frac{a}{\frac{L}{D}}))

Next Step Substitute values of Variables

∴

Nu Avg = 5 \cdot (1 + (\frac{2.4}{\frac{3m}{10m}}))

Next Step Prepare to Evaluate

∴

Nu Avg = 5 \cdot (1 + (\frac{2.4}{\frac{3}{10}}))

LAST Step Evaluate

∴

Nu Avg = 45
