A2‐in schedule‐40 steel pipe carries saturated steam at 60 psi through a laboratory that is 60 ft long. the pipe is insulated with 1.5 in of 85% magnesia that costs $0.75 per foot. how long must the steam line be in service to justify the insulation cost if the heating cost for the steam is $0.68 per 105 btu? the outside‐surface convective heat‐transfer coefficient may be taken as 5 btu/h ft2 f.
