A pipe with inside diameter 2.067 inch and wall thickness of 0.154 inch carrying steam is insulated with 2 inch of 85% magnesia covered in turn with 2 inch cork.Estimate the amount of heat loss per hour per foot of pipe if inner surface of pipe is at 250 F(121.11 0 C ) and outer surface of cork is at 90 F(32.22 0 C). The thermal conductivities (in Btu/hr.ft.F) of substance concerned are : k of steel = 26.1 & k of 85% magnesia = 0.04 & k of cork = 0.03

Q.3
A pipe with inside diameter 2.067 inch and wall thickness of 0.154 inch carrying steam is
insulated with 2 inch of 85% magnesia covered in turn with 2 inch cork.Estimate the amount
of heat loss per hour per foot of pipe if inner surface of pipe is at 250 F(121.11 0 C ) and outer
surface of cork is at 90 F(32.22 0 C). The thermal conductivities (in Btu/hr.ft.F) of substance
concerned are : k of steel = 26.1 & k of 85% magnesia = 0.04 & k of cork = 0.03

A pipe with inside diameter 2.067 inch and wall thickness of 0.154 inch carrying Q.3 steam is insulated with 2 inch of 85% magnesia covered in turn with 2 inch cork.Estimate the amount of heat loss per hour per foot of pipe if inner surface of pipe is at 250 F(121.11 OC) and outer surface of cork is at 90 F(32.22 0 C). The thermal conductivities (in Btu/hr.ft.F) of substance concerned are : k of steel = 26.1 & k of 85% magnesia = 0.04 & k of cork = 0.03 %3D Mission: i.To think critically and creatively, especially, about the use of technology to address local and global Chemical Engineering problems. ji.
