Abstract:
A viscometer assembly includes a first plate with a rail configured to constrain fluid thereon between its edges by surface tension. A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.
