Thermodynamics Reports Samples For Students

Introduction

The two sets of the experiment were conducted in which the apparatus was set in way that allows the fluids to flow and was just separated by what is referred to as the heat exchange surface. The aim of the experiment is mainly to help students to know how the heat exchanger works. The device works in a way that it enables the energy transfer from one moving fluid stream to another moving fluid stream. This is one of the heat transfer devices that do exist like the case of the car radiator and the air conditioning systems. This device ...

Introduction

In any field of engineering, precision is very important. This is mainly because any inaccuracy of any kind can have disastrous results. This is the main idea that has led to the increased push for all engineering students to do engineering drawings and dynamics even if the student does not major in any mechanical or structural fields which are mainly known to heavily rely on drawings and design.
In the specific field of study, stress and strain in any component is directly affected by its physical dimensions. This is well explained and exhibited in the experiment in which ...

The journal article was written to provide an overview of physical and chemical processes affecting changes in coral reef ecosystem. These changes are influenced by anthropogenic greenhouse gas emission (Hoegh-Guldberg, Mumby and Hooten 1737) that triggers physical processes involving laws of thermodynamics. The journal article also shows how the basic principle and theory of thermodynamics occur at global scale over a long period of time. Consequently, the physical processes influence the chemical processes that eventually lead to further changes in ocean ecosystem.
The article introduces reader to the existing phenomena of warming and acidifying of the seas (Hoegh-Guldberg, Mumby ...

Introduction

The fundamental process of thermal power plants is based on the conversion of thermal energy into mechanical energy and, subsequently, into electric power, using steam as the working fluid. According to the U.S. Energy Information System, over 67% of the electrical energy in the United States is generated through thermoelectric power plants, which use the combustion of fossil fuels such as natural gas, coal and petroleum to generate the steam necessary for the process; moreover, thermoelectric power generation accounts for an approximate 80% of all the power generation worldwide.
Thus, the electricity consumed in most homes and industries is ...

Introduction

The object of the paper is to analyze the above relationship over a range of pressures extending above and below atmospheric pressure.
Data were obtained for the pressure and temperature of a saturated steam-water mixture in equilibrium over a wide range of pressures and temperatures. The “raw” experimental data are given at the end of this document and the apparatus used are described below.

The object of this exercise is to:

a) Use the raw data to produce a table of absolute pressure .v. absolute (thermodynamic) saturation temperature over the whole range of the data provided.
b) Compare this data to equivalent data taken from steam tables.
c) Use ...

Introduction

At times, industries require the temperatures to be kept below the ambient for some processes to be effective. To do so, they must design ways to eliminate the excess heat generated by machines and introduce an artificial room temperature lower than the ambient. They must effectively eliminate temperatures above the ambient. A refrigerator is thus required in these operations. This refers to a device that can maintain the temperature below the ambient. The primary objective of a refrigeration process is to lower the temperature through heat removal. Since its invention, refrigeration has seen used in many industrial and household ...

Thermal conductivity is defined as a material’s property to conduct heat. Heat transfer across materials occurs in materials that have lower thermal conductivity and transfers faster in materials with high conductivity. It is important to determine the thermal conductivity of materials since different materials are used for different applications. For instance, materials with high conductivity are more efficient when they are used as heat sinks since they can conduct heat away faster. Those with lower thermal conductivity are often used as insulators (Callister 78).
The classical transfer of energy happens through conduction, radiation, convection or combination of all ...

Introduction

Substances vary from one another in the amount of heat needed to produce a rise in temperature in a given quantity of gas. The quantity of heat needed to change the temperature of a system is proportional to the mass of that system as well as the change of temperature. This is expressed as where Q is the amount of heat required, m is the mass of the system, c is the specific heat, and is a change in temperature. The values of specific heat depend on some extend of temperature. In small temperatures, the specific heat is considered ...

Lab Report: Measuring Specific Het of Mozzarella Cheese

In this Lab, the specific heat of mozzarella cheese was measured to be 2.46 (J/g °C) as a function of its temperature. The experiment was performed at 60 Celcius degree, and the specific heat was determined at the various temperatures. The measure was repeated fourth times in order to obtain the statistical error associated and the error was found as +/- 1.50

Introduction

The Specific heat is defined as the amount of energy required to raise in calories to produce a temperature change of 1C per gram of substance (J/g °C). Calorimetry is the measurement of heat energy changes. Calorimeter ...

ABSTRACT

This paper presents the report of the experiment carried out on the general concepts of thermal radiation. The experiment is made up of various small experiments which were carried out one after the other. The inverse square law of radiation was investigated using the Stefan-Boltzmann lamp. The relative rates of absorption of four different surfaces to two varying radiation source at different temperature were also investigated. Also, the Stefan-Boltzmann law at high temperatures, the rate of cooling of different surfaces relative to time, and the Stefan-Boltzmann relationship at near room temperature were investigated.
At the end, conclusion was ...

Introduction

During the Solubility Product experiment you calculated the Solubility Product, Ksp, for calcium hydroxide, an ionic solid that is sparingly soluble in water. This was achieved by titrating a saturated solution of Ca(OH)2 prepared at a certain temperature. The saturated, aqueous, solution of Ca(OH)2 is represented in equation form as shown below.

The equilibrium expression for calcium hydroxide is shown below.

Ksp = [Ca2+][OH–]2 Eq. 1
Equilibrium constants are temperature-dependent and the value of an equilibrium constant can be related to temperature and the Gibbs Free Energy, Gº, through the equation:
∆G°=-RTlnK Eq. 2
In this case we can substitute our ...
