Question:
A hot-water pipe (k = 35 Btu/hr-ft- o F) in a house, made of ¾ 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 f12.oF and 17.3 W/m 2 . K
(a) Determine the heat loss from the pipe.
(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.
