Viscosity of Common Alkanes
Viscosity refers to a fluid's resistance to flow, and it is influenced by the molecular structure of the substances involved. The following table provides a curated list of dynamic viscosity values for different alkanes under 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
