The model equation is validated with National Institute of Standards and Technology data on hydrocarbon liquids (C3-C10 and C12) considering the effect of molecular shape on drag force. The molecular shape is correlated well with molecular weight of hydrocarbon liquids. The accuracy of the proposed model equation is compared with the correlation. The result showed that the proposed model is more accurate. The proposed model equation predicts the viscosity over a wide range of temperature for C3-C25 with overall absolute average deviation of 5.13.
