According to stokes law, the drag force is proportional to the viscosity of the fluid , the radius r of the sphere, and the velocity (or speed) of the sphere as: (1) a steel ball is dropped into a fluid sample so that the gravitational force on the ball, mg, is larger than the buoyant force .

The speed at which a ball sinks to the ground in a fluid is directly dependent on the viscosity of the fluid. the fluids used are mainly liquids. if a ball is dropped in a viscous liquid, the speed increases at first until the opposing frictional force is.
Causing lighter fluid to rise while denser fluid takes its place. conceptually we may visualize that inside a fluid in motion one imaginary layer of fluid is sliding over another. the viscous forces act tangentially on the area between these imaginary layers, and they tend to oppose the flow. this is why if you spill honeya highly.
Consider the movement of a ball inside a viscous fluid: density of the liquid ρ. the ball is subjected to the influence of three forces: they are the weight, upthrust and the viscous force drag or liquid friction. upthrust on the ball by the liquid v ρ g 43 πr 3 ρg. viscous force 6πηv, where v is the velocity at a given a time.
(note: ideally students would wait for the ball to reach a constant velocity, however for this activity we assume the ball reaches terminal velocity very quickly, so that students can measure the time from when the ball enters the fluid until it reaches the cylinder bottom. for lessviscous, thinner, fluids, this may be very quick).
Fluid behavior. using a rheometer or a drop ball test, engineers collect the data needed to create shear stress (τ) vs. rate of shearing strain diagrams (dudy). the shear stress is calculated using the force data, and the rate of shearing strain is calculated using the deformation data. this is similar to a stressstrain diagram with solids.
Viscous flow around metal spheres math 6514, industrial mathematics katharina baamann, cornelius ejimofor, alan michaels, alec muller in this project, we analyzed the dynamic viscosity of chemicalgrade glycerin by measuring the terminal velocity of metallic spheres of varying diameters dropped in a graduated cylinder.
Each fluid was placed in a cylindrical container. ball bearings of various sizes were then dropped into container and the time it took the ball to drop a certain length was measured. using the measurements and applying the appropriate equations the viscosity of the fluid was determined. lastly, the reynolds number was calculated and analyzed.
Do not use correction fluid. 7 a steel ball is dropped from rest from a height h above the ground. the ball hits the ground after a time t. 11 a steel ball is falling at a constant (terminal) speed in still air. the forces acting on the ball are upthrust, viscous drag and weight.

Figure 14.37 (a) if fluid flow in a tube has negligible resistance, the speed is the same all across the tube. (b) when a viscous fluid flows through a tube, its speed at the walls is zero, increasing steadily to its maximum at the center of the tube. (c) the shape of a bunsen burner flame is due to the velocity profile across the tube.
Find the diameter (d) of the ball using the screw gauge. now, the radius (r) of ball can be calculated as ; r d2. clean the glass jar and fill it with the viscous fluid. place a meter scale vertically beside the jar. measure the inner diameter of the jar using a vernier calipers. hence the inner radius of the jar r can be found.

Gently drop the ball in the liquid. initially, the ball falls with an accelerated velocity until it reaches onethird height of the liquid. then it falls with uniform terminal velocity. as the ball reaches some convenient division, start the stopwatch to note its fall. as the ball reaches the convenient lowest division, stop the stopwatch.
Having a higher viscosity. put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).in general, in any flow, layers move at different velocities and the a steel ball is allowed to fall down this tube over a bring the ball with a tweezers over the tube and drop it carefully into the liquid at the.

Hence very cold thick palm oil is more viscous than very cold water. the movement of one layer of fluid over a neighboring layer is opposed by viscous forces. also when a stone or a ball bearing is thrown down a cylinder of a viscous fluid, the downward motion of the body is opposed by the viscosity of the liquid.
