Compare the heat loss from an insulated and an uninsulated copper pipe (k =400 W/m K) under the following conditions. The pipe has an internal diameter of 10 cm and an external diameter of 12 cm. The inside surface temperature of the pipe is at 110°C. The pipe is located in a space where all possible outside surface temperature of material was maintained at 30°C. The insulation available to reduce heat losses is 5 cm thick and its conductivity is 0.20 W/m K. If the furnace for heating the fluid in the pipe operating at an efficiency of 85% using natural gas priced at Cg = Php 1.00/MJ, what is the daily cost of heat loss per meter of pipe? And what is the pipe-insulator interface temperature?
