This work attempts to develop a new model for the viscosity of liquid short chain (C1–C4) 1-alcohols based on the Lennard-Jones potential. The model derived a novel equation as the mixed power and exponential function of density and temperature. When the Lennard-Jones potential took the (11.91-6) pattern, the derived equation was found in good agreement with reliable experimental data reported in literature. The R squared for the equation fitting to the 279 gathered data points that distributed in the ranges: 223.15–476.2 K and 0.1–472.8 MPa, was ≥ 0.9973. C...
