(532) for the drag force, which Figure 4.4-2 shows the settling velocity as a function of the particle diameter for the Stokes, Budryck, Rittinger & Zanke equations. In fluid dynamics an object is moving at its . 4 cm / s ) and p 2 (13. The terminal velocity is defined to be that velocity for which the drag is equal to the weight of the object; in other words, the "terminal force of drag" is by definition equal to the force of gravity on the object. The terminal velocity is reached, when there is no further acceleration. It occurs when the sum of the drag force (F d) and the buoyancy is equal to the downward force of gravity (F G) acting on the object.Since the net force on the object is zero, the object has zero acceleration.. It is important, therefore, that the material should be able to be accelerated to its terminal velocity in a straight section of pipeline, either horizontally or vertically. Problem 1. Let us study in detail the important terminal velocity examples. The terminal velocity m/s can't be measured without finding the drag coefficient. Subjects: Physical Science, Physics. Estimate the terminal velocity of the coal par- ticles in water within a centrifugal separator where the acceleration is 30.0 x g. Initial acceleration of a particle moving in a straight line is A and initial velocity is zero.
