unit, it has been suggested that we might use tim decimal multiples and submultiples of this unit, and that then the centipoise--I cp = o.oi p---could be almost exactly the viscosity of water at 2o ° C. or 68 ° F. Thus for all practical purposes in the lubricating oil business it would be sufficiently near the truth to say that the viscosity expressed in centipoise is the specific viscosity; that is, the viscosity as compared with water at 2o ° C. as a standard liquid. The true viscosity of water in absolute units is 1.0o42. Tables pared by the use of which the true viscosity may be calculated from the number of seconds required with such extensively used instruments as the Saybolt Universal, Engler, and Redwood viscosimeters.
