Liquid water flows at a mass flow rate of 2.3 kg/s through a concentric annulus tube with the inlet and outlet mean temperatures of 20oC and 80oC, respectively. The concentric annulus tube has inner and outer diameters of 10 mm and 100 mm, respectively. The inner tube wall is maintained with a constant surface temperature of 120oC, while the outer tube surface is insulated. Determine the length of the concentric annulus tube.
