Stormer viscometer

From Plastics Wiki, free encyclopedia

Stormer Viscometer - viscometer is which the fluid is placed between two cylinders. The inner cylinder rotates by the action of a falling weight. The rotational speed is determined by measuring the time required for a definite number of revolutions of the inner cylinder. The torque is determined from the weight and radius of the pulley. The viscosity of the fluid is a function of the rotational speed and torque.
