AIM. To determine the viscosity in Saybolt seconds of the given sample of.

Pour oil to be tested into the strainer by keeping the strainer on the oil cup until the oil fills up in the oil cup as well as in side well.

Withdraw the excess oil in the side well and position the thermometers in water bath and oil cup. Take a clean dry 60ml flask and place it under the orifice jet of the oil cup and center it. Pull the rubber cork open and simultaneously start a stopwatch and allow the oil into the receiving flask. Adjust the receiving flask 60ml in such a way that the oil string coming out of the jet strikes the neck of the flask to avoid foaming formation of air bubbles on the oil surface. Wait till the oil level touches the 60 ml mark, stop the watch and record the time in sec.

Repeat the experiment at different temperatures above ambient. Use specific nozzle suitable for lubricant or oil.

NOTE: For conducting experiment at different temperatures above ambient on Saybolt Viscometer, connect the heater of the water bath to a V, 50Hz, 5amps power source through a dimmer stat. Heat the water to any desired temperature while continuously stirring the water with the stirring device and occasionally the oil sample with the thermometer.

Once the temperature of the oil reaches the required temperature follow steps 6, 7 and 8.

A fluid that has no resistance to shear stress is known as an ideal fluid or in viscid fluid. Fluid with zero viscosity observed only at very low temperatures, are known as super fluids. Otherwise all fluids have positive viscosity.

A liquid whose viscosity is less than that of water is sometimes known as a mobile liquid, while a substance with a viscosity substantially greater than water is called a viscous liquid. Ten poise equal one Pascal second [Pa s] making the centipoise [cp] and millipascal second [mPa s] identical Glen E. The quantity defined above is sometimes called dynamic viscosity, absolute viscosity, or simple viscosity to distinguish it from the other quantity, but is usually just called viscosity.

It is frequently measured using a device called a capillary viscometer which is the focus of our experiment. In reservoir engineering, viscosity is of porous media has been used in conjunction with other petro-physical data to for reservoir characterization and saturations.

Viscosity, which is a dynamic property does not directly influence the conductive capacity of petroleum reservoir rocks but is extensively used not only in petroleum engineering calculations to determine the absolute or effective permeability of reservoir rocks but also in reservoir estimation of hydrocarbon fluid in-situ.

Last but not the least, equipment used in oil and gas operations, use petroleum and non-petroleum products as lubricants to operate optimally. These equipment are designed to operate optimally at certain product specification.

There proper operation depends on the viscosity of these products. Hence, accurate determination of viscosity is essential.

SAYBOLT VISCOMETER (EFFLUX CUP VISCOMETERS)

In this experiment, a fixed volume of liquids are made to flow under gravity through the capillary of a calibrated viscosimeter at a controlled temperature and the time it takes these fluids to flow are measured. The measured time are converted to centipoise using these set of equations: As stated earlier, the focus of this experiment involves measuring the viscosity of crude oil and liquid petroleum products by means of a Saybolt viscosimeter which measures the elapsed time, known as Saybolt seconds, for a volume of liquid, at specified temperatures of 70 0F and 0F, to flow under gravity through the calibrated capillary of the viscosimeter.

Generally, viscosity is usually determined by measuring the fluid flow through a capillary or orifice PNG , Lab manual, Kinematic viscosity is a measure of the resistive flow of a fluid under the influence of gravity. It is frequently measured using a device called a capillary viscometer Saybolt viscosimeter which is the focus of our experiment.Wait till the oil level touches the 60 ml mark, stop the watch and record the time in sec.

Temperature Bath Storage Pedestal

The oil cup with the water bath is supported on a stand with levelly screws. During enhanced oil recovery process, especially in the prediction of oil recoveries in thermal recovery process, oil viscosity as a function of temperature is a very important physical quantity to consider for designing the appropriate techniques and transportation, storage and handling through high pressured pipelines.

A fluid that has no resistance to shear stress is known as an ideal fluid or in viscid fluid. Efflux cup viscometers are most commonly used for fieldwork to measure the viscosity of oils, syrups, varnish, paints and Bitumen emulsions. Some of our calculators and applications let you save application data to your local computer.
