Viscometer Searle’S Pattern (Viscosity OF A Liquid BY THE Co-Axial Cylinder)

Searle's Pattern Viscometer is a type of rotational viscometer commonly used to measure the viscosity of liquids, especially in industrial and research applications. It operates on the principle of measuring the torque required to rotate a spindle (inner cylinder) immersed in a fluid, while the outer cylinder remains stationary. The inner cylinder is suspended by a torsion wire and immersed in the fluid sample.
