8.71 Water at m=0.02 kg/s and Tmi = 20°C enters an annular region formed by an inner tube of diameter D, = 25 mm and an outer tube of diameter D. = 100 mm. Saturated steam flows through the inner tube, maintaining its sur- face at a uniform temperature of T, = 100°C, while the outer surface of the outer tube is well insulated. (a) If fully developed conditions may be assumed throughout the annulus, how long must the system be to provide an outlet water temperature of 75°C? (b) What is the heat flux from the inner tube at the outlet? (c) How long must the annulus be if the water flow rate is 0.30 kg/s instead of 0.02 kg/s?
