The following data was measured in the cross-flow heat exchanger experiment using a single rod. Inlet Air Temperature (C) (Tin and T\infty): 27 Outlet Air Temperature (C): 28Average Inlet Air Velocity (m/s): 10 Heating Element Temperature (C): 550Given: The area of cross section is 0.02286 m2. The diameter and the length of the rod are 0.0125 m and 0.10795 m, respectively. Assume (air): CP = 1007 J/kg-K), Density=1.1614 kg/m3, u=184.6x10-7 (N s/m2 ) Calculate the average h and Nu. Discuss the major error sources.
