The purpose of this manual is to serve as instructional book for students‚ technical staff and instructors to assist in performing and understanding the experiments in Transport Phenomena. In the second edition‚ two new experiments on kinematic viscosity and vapor pressure determinations have been included in Fluid Mechanics and Mass Transfer sections respectively. The old experiments have been revised to eliminate errors and induce clarity. This manual will be available in electronic form from department’s

Abstract Phenytoin is generally an antiepileptic drug that is used to treat seizures and epilepsy. The influence of types of container (glass and plastic)‚ amber or non-amber‚ and storage temperatures (4‚ 25 and 40°C) on the stability of 12 extemporaneously prepared Phenytoin oral suspension was evaluated. The concentration of Phenytoin oral suspension was evaluated using high performance liquid chromatography (HPLC)‚ in which the retention time of Phenytoin was detected at 6.3 minutes. Phenytoin

The main factors of this article called “Methanol--the fuel in Waiting” explains how Methanol could both have positive and negative effects in the environment and the economy. The article discusses how methanol could be another alternative to gasoline and it is a made from natural gas‚ which makes it easier to make and use. Methanol (see Figure 1) is that it is the simplest alcohol with a chain of one carbon atom with three hydrogen atoms attached. The characteristics of this simple alcohol are

as: Methanol undergoes an oxidation reaction in the presence of catalysts‚ ethyl-alcohol‚ coal gas‚ ethylene‚ methane‚ glycol‚ glycerin‚ and carbon monoxide Production of formalin form methanol: Formaldehyde is manufactured from methanol and air either by using a silver catalyst or a metal oxide catalyst. Using Silver Catalyst: To convert methanol to formaldehyde using silver catalyst we generally carry out the reaction at an atmospheric pressure and at 600 – 720°C. The excess of methanol in the

Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when

Evaluation of gel A. pH: The pH of the various gel formulations was determined by using digital pH meter. B. Appearance: -The prepared gel bases were inspected visually for clarity‚ colour and presence of any particles. C. Homogeneity: All developed gels were tested for homogeneity by visual inspection after the gels have been set in the container. They were tested for their appearance and presence of any aggregates. D. Skin irritation test: Test for irritation was performed on human volunteers.

top-quality fuel. Get some methanol‚ some lye and some new oil at the supermarket and go ahead -- it’s a real thrill! The process Biodiesel is made from vegetable and animal fats and oils‚ or triglycerides. Chemically‚ triglycerides consist of three long-chain fatty acid molecules joined by a glycerine molecule. The biodiesel process uses a catalyst (lye) to break off the glycerine molecule and combine each of the three fatty-acid chains with a molecule of methanol‚ creating mono-alkyl esters

Selecting a Centrifugal Pump to Handle a Viscous Liquid Copyright © 2002-2011 Randall W. Whitesides‚ P.E. Introduction This course provides the student with an understanding of fluid viscosity and its effects on the performance of centrifugal pump operation. The different types and interrelation of viscosity values are discussed. Most importantly‚ it presents the established means to convert water standard pump performance curves so that they can be used to select or size pumps in viscous liquid
