Assignment Help Mechanical Engineering
Reference no: EM13963912

A wire of 6 mm diameter with 2 mm thick insulation (K = 0.11 W/mK).

If the convective heat transfer co-efficient between the insulating surface and air is 25 W/m2L, find the critical thickness of insulation. And also find the percentage of change in the heat transfer rate if the critical radius is used.
