The Society of Automotive Engineers has established an accepted numerical scale to measure the viscosity of motor oil. For examp
le, SAE 40 motor oil has a higher viscosity than an SAE 10 oil. Rank the following hydrocarbons by their expected viscosity. CH3CH2CH2CH2CH3
CH3(CH2)8CH3
CH3(CH2)11CH3
Viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid's thickness. For instance, honey has a much higher viscosity than
water .
Viscosity is measured using a
viscometer . Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest.
The aforementioned hydrocarbon are has different viscosity and so are arrange in order of their viscosity.
