Viscometric studies of binary liquid mixtures of cyclopentane (1)Â +Â branched alkanols (2) at TÂ =Â (298.15 and 308.15) K

► Viscosities of cyclopentane with branched alkanols ► Different expressions for deviations in viscosity ► Correlating equations have been used to correlate viscosity data. ► Comparisons have been made with n-alkanols.
