5- A 1 mm diameter electric wire is covered with 2 mm thick layer of insulation (k 0.5 W/mK). Air surrounding the wire is at 25°C and h 25 W/m2.K. The wire temperature is 100°C. Find for Im length: (i) The rate of heat dissipation from the wire per unit length with and without insulation. (ii) The critical radius of insulation. (iii)The maximum possible value of heat dissipation. Answer: (10.90 W/m, 2.36 W/m, 50 mm, 42.07 W/m)
