Details | The pascal second (Pa·s) is a unit used in the field of rheology, the study of the deformation and flow of matter, to describe dynamic viscosity. Dynamic viscosity is a measure of a fluid's resistance to deformation or flow due to applied shear stress or extensional stress. The pascal (Pa) is the SI unit of pressure or stress, and it is defined as one newton per square meter (N/m²). A pascal second (Pa·s) therefore signifies one pascal of shear stress applied for one second, representing the force needed to cause a fluid to flow at a certain rate. To be more specific, one pascal second (Pa·s) represents a dynamic viscosity in which a force of one newton is required to maintain a shear rate of one reciprocal second for a fluid layer that is one meter thick and has an area of one square meter (1 N/m²). It is the ratio of the shear stress experienced by the fluid to the shear rate. A higher value of dynamic viscosity (in Pa·s) indicates a more viscous fluid, meaning it requires a larger force to cause the fluid to deform or flow. In contrast, a lower dynamic viscosity value means that a fluid can flow more easily. |
