8. The falling velocity of the droplet may or may not be the same when using theforce balance method or friction factor method. If not the same, there should be areason behind that. Please choose the CORRECT answer.
(A) The falling velocities are the same, so there is no reason behind that.
(B) The falling velocities are not the same because the airflow is the creeping flow.
(C) The falling velocities are not the same because the air friction is dominant.
(D) The falling velocities are not the same because the density of the air can beignored.
(E) The falling velocities are not the same because the viscosity of the air is notconsidered when using the friction factor method.
