Example : A steel tube having k =46 W/m °C 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 1500 W/m2 °C on the inside surface, while a second fluid flows across the outside of the tube producing a convection coefficient of 197 W/m °C on the outside tube surface. The inside fluid temperature is 223 °C while the outside fluid temperature is 57 °C. Calculate the heat lost by the tube per meter of length.
