Title	A Calculation for the Viscosity of Fluid at the Critical Point
Author	Wonsoo Kim, Tong-Seek Chair
Keywords	Viscosity of fluids, Viscosity at the critical point, Theory of viscosity
Abstract	It is very difficult to measure the fluid viscosity at the critical point, there are seldom found experimental values of fluid viscosity at the critical point. Few theories can explain the critical viscosity quantitatively. A theory of viscosity previously proposed by authors¹⁰ is applied to the fluid at the critical point. This theory can be simplified as a simple form with no adjustable parameters, allowing for easy calculation. Viscosities at the critical point for some substances have been calculated, and calculated results are satisfactory when compared with the observed values.
