Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

INTRODUCTION 1 INTRODUCTION A fluid power system is one that transmits and controls energy through the use of pressurised liquid or gas. In Pneumatics‚ this power is air. This of course comes from the atmosphere and is reduced in volume by compression thus increasing its pressure. Compressed air is mainly used to do work by acting on a piston or vane. While this energy can be used in many facets of industry‚ the field of Industrial Pneumatics is considered here. The correct use of pneumatic

The flour produced from the cassava plant‚ which on account of its low content of noncarbohydrate constituents might well be called a starch‚ is known in world trade as tapioca flour. It is used directly‚ made into a group of baked or gelatinized products or manufactured into glucose‚ dextrins and other products. Starchy foods have always been one of the staples of the human diet. They are mostly consumed in starch-bearing plants or in foods to which commercial starch or its derivatives have been

Kinetics of the Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2

Lubricant A lubricant is a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles. The property of reducing friction is known as lubricity. Lubricant is a material that reduces the friction arising due to the sliding / gliding / rolling / moving of two different components in a machinery. Friction is an undesirable process that results in (i) wear and tear of the surfaces of the moving parts (ii) loss of enormous energy as
