The hot akapkan, which enters the inner pipe of a double-pipe exchanger at a speed of 5200 kg/h at 120 °C, is desired to be cooled to 22 "C. In order to cool the hot fluid, the hot fluid is fed tap water at 15 °Dec with a speed of 10780 kg/h between the inner and tooth pipes in the opposite direction. Calculate the length of the double-pipe heat exchanger to be used as a heat exchanger in these conditions.(L?)

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.
