Problem statement (cont.)
(a) Determine, symbolically, the drag forces acting on the droplet as a function of the droplet velocity, droplet diameter and air viscosity. Remember, there are drag forces along both the horizontal (x) and the vertical directions (y).
(b) Determine, symbolically, the terminal velocity of the particle along the vertical direction, VT. This is the steady velocity a particle will travel when the external drag balance the weight of the particle. What is the terminal velocity in the present case.
(c) Determine, also symbolically, the horizontal velocity, U, and the vertical velocity, V, of the droplet as a function of time by integrating the equation of motion.
(d) Integrate the velocity to determine the droplet trajectory and plot the trajectory by substituting the given data.
