It is represented in Poise - the industrial standard uses Centipoise (cP) - 1 Centipoise = .01 Poise. If the object floats on water, it means the density of the object is less than the density of water, and if the object sinks, it means that its density is more than that of water. 1.1 at 30 . 3 We found in an experiment using Ostwalds method that ethanol is more viscous than water, which is already surprising as water has stronger intermolecular bonds than ethanol as @MaxW pointed out. Copy. Water Viscosity Calculator The unit centiPoise = 0.001 Pa s and is is sometimes written mPa s. The kinematic viscosity is the dynamic viscosity divided by the density of the fluid. Methanol is the simplest alcohol and is a light, volatile, colorless, flammable liquid with a distincitve odor. N-butyl alcohol is a colorless liquid. As a result, it is more difficult to deform the surface of water than the surface of ethyl alcohol.
