High viscosity fluid has more resistance to flow than a low viscosity fluid. If viscosity of fluid is high, most likely it is difficult to pour. Hence high viscosity fluids flow less easily or slower. Low viscosity fluids (low resistance to move) flow or pour more easily and faster. Therefore oil/fluids are usually measured at the same temperature to calculate viscosity. Lubricants Viscosity and Viscosity index Q: What is Viscosity?Ī: Viscosity is a fluid’s resistance to flow at given temperature. Press Calculate button to calculate kinematic viscosity (KV) As before, use Clear button to reset and calculate a new viscosity. Calculate Viscosity use calculator 3 to calculate viscosity (KV) Enter known viscosity index (VI) and kinematic viscosity (KV) in table 3. Click Calculate to get KV As previously stated, use Clear button to start a new calculation. Enter kinematic viscosity (KV) in the second row. Similarly with known viscosity index (VI) and viscosity It is possible to calculate viscosity For example enter viscosity index (VI) in the first row of second table. Calculate Viscosity possibility is to calculate kinematic viscosity from viscosity index. Finally, press Clear button to start again. Click Calculate button to get viscosity index (VI). In the first row table 1, Enter kinematic viscosity (KV) at 40☌, In the same way enter kinematic viscosity in the second row. To calculate viscosity index we need viscosity of an oil both at 40☌ and 100☌. Standard practice for viscosity index (VI) calculation as per ASTM D2270 and ISO 2909.
