![]() ![]() Click the arrow in the check box to select the corresponding unit. The unit of acceleration of gravity, diameter of a particle, density of particle, density of medium, and viscosity of medium can be checked. Output: The viscosity of medium : 1.481481 g / m - sec. However, the most common unit of viscosity is the dyne-second per square centimeter (dyne s/cm 2) where 1 dyne 10-5 N. Input data: acceleration of gravity: 5 m / sec diameter of a particle: 4 g / m3 density of particle : 3 g / m3 density of medium is 2 m / s terminal velocity: 3 m/s click "Calculate" ,show results. Using the SI units of viscosity, shear stress was in N/m 2 and shear rate was in (m/s)/m 1/s, so dynamic viscosity has units of Ns/m 2 (newton-seconds per meter squared) or Pa s (pascal-seconds). Known data:acceleration of gravity diameter of a particle density of particle density of medium terminal velocity, Select the appropriate unit and enter a value and click on "Calculate". View all measurement unit conversion calculators on the same page (may not work with all browsers requires Iframe).Stokes's calculation: terminal velocity, acceleration of gravity, diameter of a particle, density of medium, density of particle, viscosity of mediumĬalculation of terminal velocity, acceleration of gravity, diameter of a particle, density of medium, density of particle, and viscosity of medium. The viscosity can be modified slightly up or down until you have the reducer working at its lowest temperature. Calculate the density of the air from the ideal gas law: P/ (RT) 105 Pa/ (287.05 J/kg·K × 323.15 K) 1.078 kg/m3. The calculators require that your browser has java script enabled. To calculate the kinematic viscosity of air at pressure 1 bar (105 Pa) and 50 ☌, enter a few details into the kinematic viscosity of air calculator: Convert the temperature in Celsius to kelvin: T 273.15 K + 50 323.15 K. Values lower than 0.001 will be displayed in the e-format e.g. In the first row table 1, Enter kinematic viscosity (KV) at 40C, In the same way enter kinematic viscosity 100C in the second row. To calculate viscosity index we need viscosity of an oil both at 40C and 100C. The output dynamic viscosity is given as Pas, Ns/m 2, cP, mPas, lb f s/ft 2 and lb m / (fth), while the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s. Values of 10 000 or greater will be displayed in the e-format e.g. Standard practice for viscosity index (VI) calculation as per ASTM D2270 and ISO 2909. The calculator below can be used to calculate air dynamic or kinematic viscosity at given temperatures and atmospheric pressure. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). ![]() All results shown will be equivalent values. To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. Dynamic viscosity is the tangential force per unit area (shear or tangential stress) required to move one horizontal plane with respect to the other at unit velocity when maintained a unit distance apart by the fluid (velocity gradient or rate of shear).ĬONVERSION CALCULATORS Convert between Different Units of Measurement Index of Unit Converters Sorry, your browser does not support JavaScript, which is needed to run this calculatorĭynamic Viscosity (absolute viscosity, coefficient of viscosity) Definition:Ī measure of the resistance to flow of a fluid under an applied force.
