This document is a lab assignment from Hitec University focused on designing machine elements, specifically to write a MATLAB code that shows heat flow and thermal resistance by varying insulation radius. It includes a requirement to plot these values versus insulation radius and calculate the critical radius for comparison with a specified relation. The assignment also provides necessary parameters like convective heat transfer coefficient and thermal conductivity.

- 2. Question # 01: Write a mat lab code to display heat flow (Q) and Thermal resistance (‘R’)by varying the insulation radius. Take any suitable value of all unknown required parameters. Also plot ‘Q’ and ‘Rth’ verses ‘r2’. Calculate critical radius from “Graph” or ‘Array’, and compare with following relation; Solution: Programming in Mat Lab: h = convective heat transfer coefficient r1= outer radius of pipe k = thermal conductivity l = length T= Temperature difference r2= radius of insulation Q = Heat transfer
- 3. R = Total thermal resistance. Output shown in Command window
