Question 2En. Karim recently install a hot water system operates by a solar energy. The system consists of doublepipe counter flow heat exchanger. Cold waters enters a tube at 22°C at a rate of 0.1 kg/s, while hot airenters the heat exchanger at 90°C at a rate of 0.3 kg/s. The specific heat for both cold water and hot airis cp = 4180 J/kg.K and c, = 1010 J/kg.K , respectively. The overall heat transfer coefficient based onthe inner side of the tube is 80 W/m².K. The length of the tube is 12 m and the internal diameter ofthe tube is 1.2 cm. En. Karim assigned you do the complete analysis on this hot water system includingto calculate the effectiveness of the heat exchanger. As an engineer, you have to determine:i. the heat capacity rates of both fluids,ii. the maximum rate of heat transfer (kW),iii. the effectiveness of the heat exchanger (NTU method),iv. the actual rate of heat transfer (kW), andv. the outlet temperatures of both cold water and hot air.
