Gaseous Diffusion Coefficient

Transfer Year/ Semester Year 3/ Semester 2 Lecturer Session Experiment 2: Gaseous Diffusion Coefficient Objective To determine gas diffusion coefficient of acetone Introduction because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Theory En a concentration gradient exists within a fluid consisting of […]

Introduction To Liquid Crystals Engineering

The survey of liquid crystals began in 1888 when an Austrian phytologist named Friedrich Reinitzer observed that a stuff known as cholesteryl benzoate had two distinguishable runing points. In his experiments, Reinitzer increased the temperature of a solid sample and watched the crystal alteration into a brumous liquid. As he increased the temperature further, the […]

Viscosity of Liquids

The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed, the first measures time of flow of several methanol-water solutions, from point A to point B. The second method involves dropping a foreign object, in this case a sphere, into a cylinder of glycerol and measuring the […]

Mud Density

Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density […]
