Determination of viscosity with Ostwald viscometer
... 1. Set up the temperature given by the supervisor of the measurement. 2. Measure 20 cm3 distilled water to the lower reservoir and put the viscometer to the thermostat (even the h1 level should be under the level of the water in the thermostat)! 3. Measure the weight of the empty, dry(!) pycnometer! ...

Turbulence When the Reynolds number becomes sufficiently large
... Turbulence When the Reynolds number becomes sufficiently large, the non-linear term (u ⋅ ∇ ) u in the momentum equation inevitably becomes comparable to other important terms and the flow becomes more complicated. In almost all cases the equation will have more than one solution and at least one of ...

... Newtonian Fluids • Most of the common fluids (water, air, oil, etc.) • “Linear” fluids Although any shear stress could produce a fluid deformation, a higher deformation rate requires a larger shear stress (or shear force). Therefore, a fluid still has the resistive characteristics against an appli ...

Flow Measurement
... A Reynolds number defines the flow conditions at a particular point. It is a way of representing fluidity and is a useful indicator of laminar and turbulent flow. Laminar flow exists if the Reynolds number is less than 2000, and turbulence when the number is above Flow Past a Cylinder at Re=2000 400 ...
