Evaporation Reports Samples For Students

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 ...

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 ...

Global warming is the gradual and continuous increase in the atmospheric temperature. In the nineteenth century, global warming was a mere prediction. Scientist would say that with time, the earth temperature will start to rise at a slow but continuous rate. Today, global warming is a practical experience. Studies indicate that the average atmospheric temperature increases with 0.06o Celsius, (Houghton 2009). This rate is so alarming that if nothing is done about it, the will be adversely affected. Various evidences of global warming are evidenced in the today. Increases in global temperature coupled with melting of the polar ice ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction
Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2
The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

Objectives

The aim of this experiment is to study the effective thermal conductivity of a heat pipe. This is achieved by measuring the difference in temperature across the heat pipe and another conductor made of the same material and size. The temperature measurement for both the pipe and conductor is done under identical thermal conditions.

Apparatus

- Copper-water heat pipe – The specimen whose thermal conductivity is to be found. It is represented in Figure 1.
- Solid Copper Wire – The reference material of same size.
- Thermocouple (quantity – 3) – Temperature measuring instrument (analogue).
- Multi-channel digital thermometer – Temperature measuring ...

Abstract

This experiment is meant to investigate how environmental factors such as wind, light, and heat affect the rate of transpiration in Zebra plants, Coleus, and Geranium. Among the environmental factors studied were: wind, light and temperature conducted. The study showed that the rate of transpiration was highest in coleus plant. Geranium plant showed the second highest rate of transpiration. The rate of transpiration is different from one plant species to another depending on the different morphologies and features. The rate of transpiration increased under wind and heat for all the plants tested. On the other hand, Zebra plant, recorded ...

Introduction

Esterification reactions refer to those processes between carboxylic acids and alcohols reacting together to produce esters (Smith, 2011). Ethyl ethanoate also referred to as ethyl acetate is one of the esters and is prepared through a reversible reaction between an alcohol and an acid. The process results in the production of an ester and water. The catalyst used in the reaction is sulfuric acid, which also works to remove water that is produced and thus to increase the yield of ester produced. The preparation of esters through this method is a good introduction of how equilibrium manipulation may help in increasing ...

Chapter 3: Introduction to the Atmosphere

This chapter is a basic introduction to the several properties of the atmosphere. Air is the main composition of the atmosphere and contains the majority of Nitrogen gas for 78% and Oxygen gas for 21%. The rest comprises of other gases. Although the atmospheric mixture also constitutes particulates such as dust, smoke, pollens, ash and other industrial emission. The atmosphere can be divided into homosphere and heterosphere. Different gases are scattered uniformly throughout this layer, unlike the composition in the heterosphere where each gas is separated in each layer. Located on the topmost part of the atmosphere is where the ...

Abstract

Instance of countries introducing restrictions on the amount of harmful gases released to the atmosphere is on the rise. Countries like the United States have introduced policies which govern motor vehicle pollution. Gasoline is the main component of debate. As a result several studies have been done to determine the components of gasoline. In this experiment, components of gasoline are determine by an analysis process called gas chromatogram.
Samples of gasoline used in the experiment are collected from four stations BP, Marathon, Moto-Mart and Sunoco from Ashland. The samples are then analyzed using a gas chromatogram. 10 ml was used ...
