(II) The water is ejected horizontally into the atmosphere through the convergent circular nozzle with straight axis. The inner diameter at the entrance is di, and the water density is p. The flow is assumed to be uniform at each cross-section, and the friction loss in the nozzle is negligible. The flow velocities at entrance and exit of nozzle are vi and v2 respectively. Express the horizontal force F which the flow will exert on the nozzle by di, p, vi and v2. (20 points)
