Outside diameter of concentric sphere Solution

Follow our step by step solution on how to calculate Outside diameter of concentric sphere?

FIRST Step Consider the formula

D o = \frac{q}{k e \cdot π \cdot (t i - t o) \cdot \frac{D i}{L}}

Next Step Substitute values of Variables

∴

D o = \frac{2W}{10W/(m*K) \cdot π \cdot (273.0367K - 273K) \cdot \frac{0.0477m}{3m}}

Next Step Substitute values of Constants

∴

D o = \frac{2W}{10W/(m*K) \cdot 3.1416 \cdot (273.0367K - 273K) \cdot \frac{0.0477m}{3m}}

Next Step Prepare to Evaluate

∴

D o = \frac{2}{10 \cdot 3.1416 \cdot (273.0367 - 273) \cdot \frac{0.0477}{3}}

Next Step Evaluate

∴

D o = 108.992928012398m

LAST Step Rounding Answer

∴

D o = 108.9929m
