In many scientific and industrial situation it is necessary to known fluid viscosity. Is the viscosity of the fluid flow resistance means. With high viscosity fluids have a greater resistance to flow and is not easily deformed by physical stress, but with a low viscosity fluid is thin and flow easily. Fluid viscosity can be determined using a measure known as the viscometer, which is a lot of different types. In cases where more accurate measurements are acceptable, the viscosity can be measured using a simple gravity device.
One of the most common types of viscometers decline in viscometer. This setup measures fluid viscosity as the amount of time it takes a small sphere of known size and density of a fluid within a certain distance. The field is placed in a vertical tube filled with liquid, and allowed to reach a terminal velocity as it falls.valuate the piston oscillation or vibration of a resonator immersed in a fluid, that included. Other parameters, such as the paint industry, to facilitate the physical principles can be used to derive the approximate viscosity of fluids Terminal velocity, drag force, pulling the top of the field is equal to the force of gravity, pulling him down, and the sphere ceases to accelerate, maintain a steady speed as it falls. Once the terminal velocity, fluid density and the field, and ball size is known, formula, Stokes law can be used to calculate the fluid viscosity.
Another relatively simple laboratory parameters used in Ostwald viscometer viscometer, also known as a glass capillary viscometer or U-tube viscometer. This U-shaped glass tube, the device consists of two bulbs, the lower part of the left hand of the U, and the high part of labor law. It is held in a vertical fluid produced in the upper bulb, and then allowed to flow back into the lower bulb, over the last two marks on the pipe. Viscosity of the fluid can be determined by factoring in diameter glass tube, how long does it take for fluid flow past the two marks, and that the fluid density.
Laboratories, which require precision measurements can be used by sophisticated electronics viscometers and viscosity to evaluate the piston oscillation or vibration of a resonator immersed in a fluid, that included. Other parameters, such as the paint industry, to facilitate the physical principles can be used to derive the approximate viscosity of fluids. These measurements are often known as the kinematic viscosity of fluid flow resistance means based on the weight.
Zahn Cup and the Ford viscosity cup gravity kinematic viscosity measuring devices used in the examples. In these devices, liquid - paint, Zahn cup, motor oil or Ford Cup - drains through a small hole in the bottom of the bowl, as it is high. Smooth flow of fluid flowing to a certain point where it breaks up into drops. Depending on the fluid viscosity, fracture will take place at different times. Kinematic viscosity of the measure can be found by multiplying the second time in a cup of specification number, which is calibrated in the appropriate fluid.
