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

The local atmospheric pressure is 88 kPa. Now‚ heat is transferred to refrigerant-134a until the temperature is 15°C. Determine (a) the final pressure‚ (b) the change in the volume of the cylinder‚ and (c) the change in the enthalpy of the refrigerant-134a. 3. Determine the specific volume of superheated

Conclusions The purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight. In the lab‚ the substances with the higher atomic weights had less specific heat. From this‚ we can conclude that specific heat and atomic weight have an inverse relationship‚ meaning as one decreases the other increases. The reason for this is because if atoms are small‚ or light‚ they have the ability to pack tightly together‚ leaving almost no space between them

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

UNSTEADY STATE HEAT TRANSFER Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems‚ design of conventional space and water heating systems‚ cooling of electronic equipment‚ and many manufacturing processes (Campos 3). Unsteady state conduction is the class of heat transfer in which the temperature of the conducting medium varies with time and position. This occurs frequently in

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

Night Narrative Essay The book Night‚ written by Eliezer Wiesel is about his experience in the holocaust and the pain and suffering him and the jews went through. He was taken from his home as a young boy and put into multiple ghettos before he was shipped off to Auschwitz. There he was separated from his family and left with his father‚ Shlomo Wiesel. He was sent to different camps and stuck with his father until the end. But at the last camp they stayed at‚ his father was sent to the crematorium
