During a high reynolds number experiment, the total drag force acting on a spherical body of diameter d = 12 cm subjected to airflow at 1 atm and 5°c is measured to be 5.9 n. the pressure drag acting on the body is calculated by integrating the pressure distribution (measured by the use of pressure sensors throughout the surface) to be 4.9 n. determine the friction drag coefficient of the sphere. take the density and kinematic viscosity of air at 1 atm and 5°c as rho = 1.269 kg/m3 and v = 1.382 × 10–5 m2/s and the drag coefficient of the sphere in turbulent flow as cd = 0.2. (round the final answer to four decimal places.)
