Question

A circular tube of outer diameter 5 cm and inner diameter 4 cm is used to convey hot fluid. The inner surface of the wall of the tube is at 80°C while the outer surface of the wall is at 25°C. What is the rate of heat transfer across the tube wall per unit length of the tube at steady state at thermal conductivity 10 W/mK? a) 16487 W/m. b) 15478 W/m. c) 14678 W/m. d) 15487 W/m.

Step 1

We need to calculate the rate of heat transfer per unit length through a cylindrical tube wall at steady state. We are given the outer diameter (5 cm), inner diameter (4 cm), the temperatures at the inner (80°C) and outer surfaces (25°C), and the thermal Show more…
