For nickel cobalt separation extractant, what’s the relation of viscosity dynamic number cP and mm2/s?
As regular viscosity data, our DY272 nickel cobalt separation extractant is less than 142cP at 25°C usual temperature, but some company would like to use the viscosity unit of mm2/s, how to convert them?
We know that every goods in different temperature will have different density, bnickel cobalt separation extractantecause if the temperature is higher, the volume will be bigger, with same weight, the density will be lower. So usually we only talk room temperature 25°C. As same reason, for DY272 nickel cobalt extractant, in different temperature the viscosity will be different, so we only mark the viscosity is less than 142cP at 25°C room temperature. If at 50°C working temperature, the viscosity will be less than 37cP.
For DY272 nickel cobalt separation extractant, if we convert to mm2/s, the viscosity will be 154mm2/s at 25°C, in working temperature 50°C, the viscosity will be 40mm2/s.
It means η=ν. ρ. Explain: The unit of dynamic viscosityηis cP, the unit of dynamic viscosity v is mm2/s, the density of DZ272 is about 0.92. So 1Cp=1mm2/s*0.92.
The relationship between the dynamic viscosity measured in centipoise (cP) and the kinematic viscosity measured in square millimeters per second (mm²/s).
To convert between these two units for a nickel cobalt extractant or any other fluid, you need to know the density of the fluid at the temperature of interest. The density is typically given in grams per cubic centimeter (g/cm³), which is numerically equivalent to kilograms per cubic meter (kg/m³).
For example, if you have a nickel cobalt extractant with a dynamic viscosity of 100 cP and a density of 0.9 g/cm³.
It’s important to note that the density of the extractant can vary depending on its composition and the temperature, so it’s best to use the density value that corresponds to the specific conditions under which the viscosity is being measured.
