Air at 1atm and 300K enters a compact exchanger like type A shown in Figure 10.6 with a velocity of 10m/s. Calculate the heat transfer coefficient. The following is the relevant air properties. =1.1774kg/m3,cp=1.0057kJ/kgK,=1.983105kg/ms, Pr=0.708. The aluminum tube has an inner diameter of 1.3cm and conductivity of 237 W/mk. Water flows inside the tube with a heat transfer coefficient of 1000W/m2K. Assume a fin efficiency of 0.9, Calculate the overall heat transfer coefficient
