The viscosity of a liquid is a measure of its resistance to flowâthe opposite of fluidity. Viscosities are expressed in units called poises. At room temperature, the viscosity of water, which flows readily, is about 0.01 poise. Molasses has a viscosity of about 500 poises and flows like ...
Staple fibers are short fibers that have been produced and then cut. Afterward the shorter fibers are blended together for smoother look and a different mix of characteristics, such poly-cotton t-shirts that are soft but do not shrink.
