Solve using the methodology : Known, Find, Schematic Diagram, Assumptions, Properties, Analysis and Comments. 8. A thin electrical heater is wrapped around the outer surface of a long cylindrical tubewhose inner surface is maintained at a temperature of 6°C. The tube wall has inner andouter radii of 24 and 78 mm, respectively, and a thermal conductivity of 10 W/m K.The thermal contact resistance between the heater and the outer surface of the tube(per unit length of the tube) is R' t.c = 0.01 m · K/W. The outer surface of the heater isexposed to a fluid with To = -10°C and a convection coefficient of h = 100 W /m2. K.Determine the heater power per unit length of tube required to maintain the heater atTo = 25°C

Given Internal temperature = 6 C Outer radius = 78 mm Inner radius = 24 mm Thermal conductivity =…
