3. Air flows over a smooth plate. Various quantities are to be determined at x = 0.3 m. Edge effects are negligible and the upper surface of the plate is to be considered. T.= 40C, V = 10 m/s, T. = 5C, A. = 2.0 m L = 2m Determine the following: Rex=0.3m, &x=0.3m, Nux, and hy. Air Properties: p= 1.164 kg/m’, Cp = 1007 J/kg K, = 1.872 x 10 kg/m.s, Pr = .7282, k =.02662 W/ mK Hint: Begin with determining Xer.
