2 Question 3 (6 Points) Cold water is flowing though the center of an aluminum 2024-T6 pipe with a diameter of 500mm, a wall thickness of 7mm and a length of 5m. The pipe is covered with a 40mm thick layer of insulation. The water is at a temperature of 11 °C and the air surrounding the pipe is at 150 °C. Some transport properties are shown in the table below. ts nents ns 1. Sketch the equivalent thermal circuit diagram for the presented case. Include the appropriate equation for each of the resistances. 2. What is the heat transfer rate through the pipe and insulation? 3. What is the heat flux at the inner pipe surface and the outer surface of the insulation? 4. What is the temperature of the outer surface of the insulation? urse 5 k Box L Insulation Pipe inner diameter: 500mm Pipe wall thickness: 7mm Insulation thickness: 40mm Length: 5m Information Pipe Information T.,water hwater Toe, water: 11°C T.,air: 150°C hwater: 200 W/m2/K har: 50 W/m2/K K2024-T6: 180,7 W/m/K Kinsulation: 3.53 W/m/K
