Viscosity meaning in science2/9/2024 Other common units of viscosity include centipoise (cP) and poise (P), where 1 P = 0.1 Pa So, the dimension of viscosity (M) is kg m⁻¹ s⁻¹, which is equivalent to the SI unit pascal-second (Pa The dimensions of viscosity (M) can be expressed as: A higher viscosity means greater resistance to flow, and a lower viscosity means the fluid flows more easily. The formula shows that the shear stress is directly proportional to the velocity gradient and the dynamic viscosity. (du/dy) is the velocity gradient, which indicates how the velocity of the fluid changes with respect to the distance in the direction of flow.s), which represents the fluid’s resistance to flow.η is the dynamic viscosity (measured in pascal-second, Pa. ![]()
