Extracted text: A long hollow cylinder has inner and outer radii 50 mm .and 150 mm respectively. It generates heat at a rate of 1 kW/m3 (k = 0.5 W/m°C). If the maximum temperature occurs at radius of 100 mm and temperature of outer surface is 50°C, find: (i) Temperature at inner surface, and 5) Maximum temperature in the cylinder.
