Problem 1 (10 points): determine the convection heat transfer coefficient, thermal resistance for convection, and the convection heat transfer rate that are associated with air at atmospheric pressure in cross flow over a cylinder of diameter d = 100 mm and length l = 2 m. the cylinder temperature is ts = 70◦c, while the air velocity and temperature are v = 3 m/s and t[infinity] = 20◦c, respectively. plot the convection heat transfer coefficient and the heat transfer rate from the cylinder over the range 0.05 m ≤ d ≤ 0.5 m
