The unit of viscosity is
The unit of viscosity is Poise. Viscosity measures a fluid’s resistance to flow. It is defined as the ratio of shear stress to shear rate within a fluid. The Poise is the unit used to quantify viscosity, named after French physiologist Jean Léonard Marie Poiseuille, who made significant contributions to fluid dynamics.

The unit of viscosity is Poise; option [A]. Viscosity is a measure of a fluid’s resistance to flow, describing its internal friction. It is defined as the ratio of shear stress to shear rate within the fluid. The Poise is the standard unit used to quantify viscosity. It is named after French physiologist Jean Léonard Marie Poiseuille, who made significant contributions to the understanding of fluid dynamics and the study of viscosity. The Pascal, on the other hand, is a unit of pressure, while Poiseuille is a unit used to measure flow rate in fluid dynamics, particularly in the context of laminar flow through cylindrical tubes, named after Jean Léonard Marie Poiseuille. Therefore, the correct unit for viscosity is Poise, denoted by the symbol “P”.
