The coefficient of viscosity is a measure of resistance to flow of the fluid. In general, gas viscosity is less than liquid viscosity. The inverse of viscosity is called fluidity [McCain, 1990]. Thus, a fluid with a large viscosity has a low fluidity. ... The unit of dynamic viscosity μ is centipoise.
