Importantly, the graphs can be saved for use in the users own reports. Registration takes just seconds and only requires name, company and email address. g is a constant, which is 9.8 m/s2 (acceleration due to gravity) and v is the velocity of the ball falling through the liquid, and a is the radius of the ball.
Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above 70 mm 2 /s at 100 C. The final equation youll need to calculate the liquids viscosity is this: Viscosity (2 x (ball density liquid density) x g x a2) ÷ (9 x v). More detailed results, including graphs (some in 3D), can be accessed by logging in (existing users) or registering (new users). Table 1 given in this practice applies to petroleum products with kinematic viscosities between 2 mm 2 /s and 70 mm 2 /s at 100 C. This free-of-charge Webtec app is the company’s ‘light’ version. This gives 0.0102 cp, but corrections are needed for. First, the viscosity for Mg (0.7) (28.967) 20.3 at p 1 atm and T 75☏ is read from Fig. 2 in Gas formation volume factor and density : The viscosity is determined using the charts of Carr et al. Plus other cooking conversions such as butter weight, and gas mark temperatures. The formation volume factor is calculated from Eq. SAE J300 Viscosity table, SAE J300 Viscosity chart shown above is January 2015 revision. Online Conversion is a resource for weights, measures, calculators. To see the effects on viscosity of fluctuations in temperature or pressure, the user simply alters the values in these fields accordingly, making hydraulic measurement and control easy to achieve. High viscosity thicker oils have strong film strength to protect metal to metal contact during high temperature and heavy load. Using Webtec’s app, engineers simply select the oil being used, along with the system temperature (☌) and pressure (bar), hit the ‘submit’ button and up pops the viscosity (cSt). These oils are most-often badged in terms of their ISO number or grade, where common grades for hydraulic circuits include ISO 32, 46 and 68. Hydraulic fluid suppliers provide oils with different viscosities. On the other hand, the kinematic viscosity tells about the speed the fluid reaches when a particular force is applied to the fluid.Webtec has launched a new on-line hydraulic oil viscosity calculator app which calculates the viscosity of hydraulic oil at different pressures. When choosing between the two viscosities, it is worth noting that dynamic viscosity tells us about the force required to move the fluid at a certain speed. where K is the value of a liquid with known viscosity and density such as water.
The viscosity is calculated with Equation 1. This calculator can be used to calculate bearing frequencies based on manual input of bearing geometry data. The larger the force or stress needed to move the plate, the more viscous the fluid is. The liquid is then drawn through the side 2 of the U-tube by use of suction and lastly, the flow is time between marks C and B.
