Question
(a) If the cost of producing the hot water is $0.10 per kWh, 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.
