Normal forces generated in the flow between two-rolls, one rotating and the other fixed, are measured. Water and glycerin-water solutions are used in the experiments and the forces measured under the usual experimental condition are in good agreement with one-dimensional theoretical predictions obtained by Cameron using the Reynolds equation and the half Sommerfeld condition. A thin liquid film is produced on the surface of the rotating roll under the usual experimental conditions. But when the liquid film is stripped off with a spatula, the measured normal force is reduced. In the case of a small quantity of supplying fluids and the low speeds of rotating, the measured normal force is negative for water but positive for glycerin-water solutions.
