A steel tube having k = 46W/m · ºC has an inside diameter of 3.0 cm and a tube wall thickness of 2 mm. A fluid flows on the inside of the tube producing a convection coefficient of 1500W/m2 · ºCon the inside surface, while a second fluid flows across the outside of the tube producing a convection coefficient of 197 W/m2 · ºC on the outside tube surface. The inside fluid temperature is 223ºC while the outside fluid temperature is 57ºC. Calculate the heat lost by the tube per meter of length.
