5.3.4 Plastic lubricants

A. Design relations

Plastic lubricants with thickening agents, over the temperature range 293 < T < 413 K, are governed by the proposed interpolation formulas (Froishteter and Tambieva, 1971). For hydrocarbon lubricants,

\[\label{eq1} \lambda=\lambda_0[1+0.97C^{1.53}-0.0057C^{1.18}(T-273)] \tag{1}\]

\[\label{eq2} c_p=c_{p_0}[1+1.035C^{1.09}-0.0057C^{1.56}(T-273)] \tag{2}\]

and for lubricants with soaps and other thickening agents
