For example syrup has a higher viscosity than water.
Viscosity measurement flow cup.
The ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom.
This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes using a viscosity disc calculator.
The viscosity of a fluid is a measure of its resistance to deformation at a given rate.
Under ideal conditions this rate of flow would be proportional to the kinematic viscosity expressed in stokes and centistokes that is dependent upon the specific gravity of the draining liquid.
The measured kinematic viscosity is generally expressed in seconds s flow time.
Why get a viscosity cup viscosity cups like ford and zahn cups are handy tools at as a painter.
Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion.
Additionally knowing the viscosity of your paint allows you to have a reference range so you can select equipment settings that will let you achieve a.
Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times.
However the conditions in a simple flow.
Mxbaoheng nk 2 viscosity cup 50ml viscometer flow cup mixing thinning tool 70 370cst for paint industry viscosity measurement 3 0 out of 5 stars 1 31 56 31.
Viscosity cups consist of a hollow cylinder which terminate in a nozzle in the bottom.
For liquids it corresponds to the informal concept of thickness.
The unit of measurement is centipoise a universally used metric unit of viscosity.
A flow cup is a cup of a specified size and volume with an overflow channel at the top and a hole of a defined size in the bottom.
The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.
Viscosity flow cups are very easy to use instruments of anodized aluminum with a stainless steel orifice for measuring the consistency of paints varnishes and similar products.
Whether your spraying wood finishes industrial enamels or anything in between a paint viscosity cup allows you to know just how thin your paint is.
Excess fluid is collected in the gutter channel.
The viscosity is established in terms of the time in seconds in which a precisely controlled volume of fluid flows out through a nozzle of the viscosity cup.
