Calculate the heat loss per linear foot from a 3-in. steel pipe (id = 3.07 in.,od = 3.5 in., k = 25 btu/hr-ft-ºf) covered with 0.5-in thick insulation (k = 0.11 btu/hr-ft-ºf). the pipe transports a fluid at 300 ºf with an inner unit-surface heat transfer coefficient of 40 btu/hr-ft2-ºf and is exposed to ambient air at 80 ºf with an average outer heat transfer coefficient of 4.0 btu/hr-ft2-ºf.
