Variation of Viscosity of Castor Oil and Silicone oil with Pressure and Temperature

Dr. Jamuna Prasad [3]


Abstract: Variation of viscosity data is reported for castor oil and silicone oil with pressure up to 6kbar and temperature from 30 ?C to 90?C with accuracy ?1 percent, using a rolling-ball viscometer. The results of viscosity of these systems with temperature and atmospheric pressure are also reported with estimated accuracy ?1 percent. The experimental data have been represented by empirical relations for pressure and temperature variation. This data has also been used to determine the activation energy of viscous flow as a function of pressure and differential pressure coefficients as a function of pressure and temperature. At the end, Kiran and Sen Observations are also checked with the average modulus of deviation (MD) being less than 1.8 percent.
