Corrosionpedia - 6 Ways to Measure Fluid Viscosity

Viscosity is defined as the degree up to which a fluid resists the flow under an applied force; it is measured by the tangential friction force acting per unit area divided by the velocity gradient under conditions of streamline flow. An important rheological measurement that is closely related to the resistance to flow is called viscosity. Dynamic Viscosity Formula - Answer: From the formula of dynamic viscosity we can find the share stress, τ = η * γ and then substituting the values, τ = (0.018 Pa*s)* (0.35 s (-1)) = 0.0063 Pa τ = 0.0063 Pa = 0.0063 N/m 2 Kinematic Viscosity Formula - Answer: The dynamic viscosity of mercury is η= 1.526 Pa*s. First calculate the density mass of mercury using the formula ρ = mass/volume. ρ = 2 Kg/ 1 L = 2 Kg/ 0.001 m 3 = 2000 Kg/m 3 Then calculate the kinematic viscosity using its formula, How to Calculate Viscosity | Powerblanket Heating Solutions Oct 24, 2018

Oil Viscosity Index and Viscosity Temperature Relation Identify two reference oils whose kinematic viscosity at C coincides with the kinematic viscosity of the unknown oil (from the look-up chart of ASTM standard). Pick-up the kinematic viscosity of two identified reference oils at C In reference to illustration above, now a, b, and c are known. Viscosity index calculator - Evonik Oil Additives

Viscosity of Fluids & Velocity Gradient - Fluid Mechanics

Calculate the dynamic viscosity (η) in pascal seconds (Pa s) from the expression η=KL/w, Where, L = the angular momentum in Newton meters, w = the angular speed in radians per second. The constant (K) of the instrument is determined using a liquid of known viscosity or by reference to tables supplied by the instrument manufacturer.
