Consider a symmetrical airfoil with 1 m chord in a wind tunnel

Consider a symmetrical airfoil with 1 m chord in a wind tunnel experiment where free stream velocity is 37 m/s at sea level conditions. Using the flat plate approximation, estimate the viscous drag at zero angle of attack. (Take poo = 1.225 kg/m3 and oo = 1.778 x 10-5 kg/ms)
