In a countercurrent double-pipe heat exchanger, the hot oil entering the inner tube at 420 K with a flow rate of 60 g/s is required to be cooled to 320 K. In the space between the outer tube and the inner tube of the heat exchanger, cooling water flows at the same linear speed as the oil. Cooling water enters the heat exchanger at 290 K. The inner tube inner diameter of the heat exchanger is 25 mm and the outer tube inner diameter is 40 mm. Calculate the length of the heat exchanger. The oil side heat transfer coefficient is 1.6 kW/m2 K, and the water side heat transfer coefficient is 3.6 kW/m2 K. The densities of oil and water can be taken as 0.8 and 1.0 g/cm3, respectively, and the specific heats of oil and water can be taken as 2.0 and 4.2 kJ/kg K, respectively. Wall effects can be neglected. Flow cross-sectional area = (PI)*D2 /4 F2
