demonstrate the working principles of industrial heat exchangers ii. To investigate the efficiency of the heat exchanger in parallel and counter flow arrangements 1.0 INTRODUCTION A heat exchanger is equipment in which heat exchange takes place between 2 fluids that enter and exit at different temperatures. The main function of heat exchanger is to either remove heat from a hot fluid or to add heat to the cold fluid. The direction of fluid motion inside the heat exchanger can normally categorised as

Specific Heat Lab Report “Here are the facts we confront; No one is against conservation. No one is against alternative fuel sources.” – J. D. Hayworth Research Question: Does the number of hydrocarbons that a fuel is composed of affect how much it will ignite? If so‚ consider the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the

Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy required

HEAT ENGINE WORKING CYCLES An engine is a device which transforms one form of energy into another form. However‚ while transforming energy from one form to another form‚ the efficiency of conversion plays an important role. Normally‚ most of the engines convert thermal energy to mechanical work and therefore they are called ‘heat engines’. Heat engine is a device which transforms the chemical energy of a fuel into thermal energy and utilizes this thermal energy to perform useful work. Depending

If you’re down in these months‚ may be suffering from seasonal affective disorder (SAD). In the US‚ people have fought depression with an extra dose of artificial light during the day. Now‚ a new study found that light therapy is effective for treating other types of depression as well. For example‚ people with SAD may have a feeling that lingers over the winter months‚ sometimes even

The Process of Paradoxical Heat Sensation Vy Tran West Covina High School Abstract The following research study examined the effects of using a warm stimulus cold stimulus instead of a hot stimulus and a cold stimulus to perform a sensation known as paradoxical heat. In the process of paradoxical heat sensation‚ a hot and cold stimulus is synchronically stimulated giving off a feeling we believe is very hot but is actually two stimuli activating together. The
