Stokes' Law and Terminal Speeds Stokes calculated the drag force on a sphere at low speeds as , where Î· is the viscosity, r is the radius, and v , is the speed. Terminal speed for a sphere falling under gravity in a medium such as air or water.... Before we go to terminal velocity calculation, we must first calculate the drag force working at the object. Drag force is a kind of friction when an object moving through fluid such as water or atmosphere.

**How to determine the terminal velocity of a liquid Quora**

Terminal Velocity Terminal velocity depends on the radius of the sphere so if radius is made n-fold, terminal velocity will become n2 times. Greater the density of solid, greater will be the terminal velocity Greater the density and viscosity of the fluid, lesser will be the terminal velocity. If > o, then terminal velocity will be positive and hence the spherical body will attain constant...25/10/2018Â Â· To calculate terminal velocity, start by multiplying the mass of the object by 2. Then, multiply that number by the acceleration of the object due to gravity and write your answer down. Next, multiply the density of the fluid the object is falling through by the projected area of the object. Then, multiply that number by the drag coefficient. Finally, divide your first answer by your second

## Using Stokes Law How To Find Terminal Velocityy

### The previous theory used Newtonâ€™s law of motion for describing the falling ball reaching a terminal velocity; thus, the net force of gravity, buoyancy, and drag is zero: The drag force is expressed in the third term on the right side of the equal sign according to Stokesâ€™ law, which is valid in Ref. 1.

- Derivation of Stoke's Law A spherical grain settling through a fluid at low Reynolds numbers is acted upon by a downward-directed force of gravity (F G ), an upward-directed force of bouyancy (F B ), and an upward-directed force of fluid drag (F D ), which tends to retard the downward settling of the grain.
- (a) What is the terminal settling velocity of a particle with a specific gravity of 1.4 and a diameter of 0.010 mm in 20Â°C water? (b) Would particles of the size in part (a) be completely removed in a settling basin with a width of 10.0 m, a depth of 3.00 m, a length of 30.0 m, and a flow rate of 7,500 m 3 /d?
- The law, first set forth by the British scientist Sir George G. Stokes in 1851, is derived by consideration of the forces acting on a particular particle as it sinks through a liquid column under the influence of gravity .
- Knowing the terminal velocity, the size and density of the sphere, and the density of the liquid, Stokes' law can be used to calculate the viscosity of the fluid. A series of steel ball bearings of different diameters are normally used in the classic experiment to improve the accuracy of the calculation. The school experiment uses
