An insulated heating pipe that is made from steel (k = 45 W/m K) with an inner radius of 150 mm and an outer radius of 155 mm. The pipe is coated with 100 mm thickness of insulation having a thermal conductivity of k = 0.06 W/m K. Air at Ti = 60 °C flows through the pipe and the convective heat transfer coefficient from the air to the inside of the pipe has a value of hi = 35 W/m2 K. The outside surface of the pipe is surrounded by air which is at 15°C and the convective heat transfer coefficient on this surface has a value of ho = X (W/m²K). (a) Calculate the heat loss through 50 m of this pipe. (b) Find the critical insulation radius, (c) Sketch the schematic of the system with complete labeling. Note: X = Last 2 digits of Student ID Number For example: if your ID Number is 202006719 then X = 19.
