A type 316 stainless steel pipe has a 6 cm inside diameter and an 8 cm outside diameter with a 2 mm layer of 85% magnesia insula- tion around it. Liquid at 112°C flows inside with ħ¡ = 346 W/m²K. The air around the pipe is at 20°C, and ħ, = 6 W/m²K. Calculate U based on the inside area. Sketch the equivalent electrical circuit, showing all known temperatures. Discuss the results and suggest an improved design. [T, = 96.36°C]
