Transcribed Image Text:
A hot-water pipe (k = 35 Btu/hr-ft-OF) in a house, made of % inch schedule 40 pipe is 40 ft long and contains water at 50°C. The air around the pipe is at 5°C. The heat transfer coefficients inside and outside the pipe are, respectively, 200 Btu/hr-ft2.°F and 17.3 W/m?. K (a) Determine the heat loss from the pipe (5 points). (b) 4 group of engineers come up a solution to reduce the heat transfer with insulation added to the pipe of 0.5, 0.25, 0.8 and 1.0 inch with k = 0.2 Btu/hr ft-°F. They claim that their insulation design is optimum. Provide your recommendations on the economic insulation design with appropriate explanation (5+5+5+5 points). %3!
