Answer to Question #75430 in Mechanical Engineering for Ben Garland

Question

The thermal resistance of the pipe wall can be ignored due to the pipe's relatively low wall thickness. Based on the below worked example we can see accounting for the mean pipe wall thickness the difference between the above and below answer's is 2.60pc.

If the wall thickness was to increase it would be prudent to use the logarithmic expression as this accounts for the change in area which becomes more important the thicker the pipe wall.

However, as no dimensions have been provided for the pipe wall thickness we can assume that the pipe wall is this and thus have a negligible effect impact.

Determining the width of the plate:

W=2πr_(mean )
