WebThe system draws oil up to the tubes as per the manual method, though in this case all the tasks are controlled by a computer program. The system does not require an operator to monitor and time the oil flow. Important Conclusions. Viscosity is a critical fluid property, and viscosity monitoring is essential to oil analysis. WebViscosity is the measure of a fluid’s resistance to flow (shear stress) at a given temperature. As flow conditions vary, not all fluids retain an unchanged viscosity. A fluid in which the viscosity changes with flow … WebMotor oil has greater viscosity when cold than when warm, and so pressure must be greater to pump the same amount of cold oil. Figure 5. Poiseuille’s law applies to laminar flow of an incompressible fluid of viscosity η through a tube of length l and radius r.
