Mehrotra

Method of Mehrotra The Mehrotra method [24] has been derived with 273 heavy (Af 100 gmol-1) hydrocarbons such as n-paraffins, 1-olefins, branched paraffins and olefins, mono- and polycycloalkanes, and fused and nonfused aromatics. Based on 1300 individual dynamic viscosity-temperature values for these compounds, the following one-parameter equation has been obtained by employing regression analysis  [Pg.72]

At atmospheric pressure, hydrocarbon viscosities can be estimated by two methods the ASTM method and that of Mehrotra (1990). [Pg.128]

In Mehrotra s method, the dynamic viscosity is expressed as a function of temperature according to the relation ... [Pg.128]

The Mehrotra and ASTM methods apply with acceptable accuracy only for viscosities between 1 and 1000 mPa s. The average error is about 20%. The largest spreads are obtained at low and very high viscosities. [Pg.129]
