You are a chemical engineer and your boss asks you to design a concentric tube heat exchanger with a tube length that you need to assume (do not
assume 1 m). The cold water (2.5 kg/s) is flowing in the inner tube with Di = 25 mm while the hot water (1 kg/s) is in the outer annulus of Do = 45 mm.
The inner tube has a thickness of 5 I mm (k=16 W/m K). The inlet temperature for hot and cold water are 85 °C and 20 OC, respectively. Given that the cold
side heat transfer coefficient, hi =2250 W/m² K and hot side heat transfer coefficient, ho = 4000 W/m² K, calculate the Tco and Tho for your assumed L.
Take CP,C* 4183 //kg Kand CP,1 h = 4200 //kg K. Note: You can assume your flow to be either parallel flow or counter flow
