A stainless-steel tube having 2 cm-I.D. and 3 mm wall thickness is insulated with a 3-cm thick layer of fiberglass. Liquid water flows through the tube at velocity 0.2m/s. The water is at 80 C and the ambient air temperature is 20 C. If the outside heat transfer coefficient to the air is 6 W/m-K, calculate the rate of heat loss per meter length of the tube. Thermal conductivity of steel: 20 [W] m K W Thermal conductivity of fiberglass: 0.05 [- "m K
