Calo‐visco‐densimeter: A multipurpose apparatus
Chemical Engineering & Technology, 1991AbstractA multipurpose apparatus was designed, built and operated with the aim of a simultaneous determination of enthalpy of mixing, heat capacity, kinematic viscosity and density of liquid mixtures at 240 < T < 370 K and 1 < p < 25 bar. Its operation was monitored by a PC. Details of design and the first experimental results are presented.
