Hot water at 50 c is routed from one building in which it is generated to an adjoining building in which it is used for space heating. transfer between the buildings occurs in a steel pipe (k 60 w/m k) of 100-mm outside diameter and 8-mm wall thickness. during the winter, representative environmental conditions involve air at t 5 c and v 3 m/s in cross flow over the pipe.

(a) if the cost of producing the hot water is $0.10 per kw h, what is the representative daily cost of heat loss from an uninsulated pipe to the air per meter of pipe length? the convection resistance associated with water flow in the pipe may be neglected.

(b) determine the savings associated with application of a 10-mm-thick coating of urethane insulation (k 0.026 w/m k) to the outer surface of the pipe.
