MATHEMATICAL MODELLING OF MICROWAVE HEATING OF FOOD By M . SHIVA KUMAR ( 04AG1008 ) Under the guidance of PROF. SURESH PRASAD ABSTRACT • The use of microwaves in the food industry is attributed to the lower time needed to increase the temperature of foodstuffs compared to the traditional heating methods. •However‚ the heating is not uniform and the products show hot and cold spots. • In order to analyze the behaviour of foods heated by microwave oven‚ a mathematical method was developed

------------------------------------------------- Reflections theory Introduction In this report I will be comparing two reflective theories‚ outlining their similarities and differences. I will be choosing the one I believe to be the best in my opinion. This will be the one I will be using in my end of year reflective account. The two reflective theories I will be looking at are‚ Johns Model of Structured Reflection and Gibbs’s Reflective Cycle. Theories There are two main differences between

Hess’s Law Mengyuan Wu (Millie) 7 January‚ 14 Aim: The purpose of this experiment is to determine the enthalpy change for the reaction: Introduction: It is impossible to measure the enthalpy change for this reaction directly because the process cannot be controlled. However‚ you can calculate this enthalpy change by using the Hess’s Law. Pre- lab Calculations: Calculation 1: Required Masses for Reaction The ratio of and is required to be 1:100 for Table 1: Calculation

Looking for a Gas Gas is everywhere. There is something called the atmosphere. That’s a big layer of gas that surrounds the Earth. Gases are random groups of atoms. In solids‚ atoms and molecules are compact and close together. Liquids have atoms that are spread out a little more. Gases are really spread out and the atoms and molecules are full of energy. They are bouncing around constantly. Gases can fill a container of any size or shape. It doesn’t even matter how big the container is. The

Introduction: The point in a body at which the resultant pressure acts when the body is immersed in a fluid. The apparatus for center of pressure. Objective: The object of this experiment was to calculate the hydrostatic force a fluid exerts on a submerged plane surface and then compare the experimental hydrostatic force to the theoretical hydrostatic force. Theory: The apparatus defining the physical dimensions‚ this nomenclature will be used throughout this theory. Whilst the theory

QUESTION 1: (a) Identify ONE natural process that has been most significant in the formation of a natural feature shown on you map/diagram. Justify why this is the most important process forming this feature. The Muriwai coastal environment is a unique environment where the coastline and relief is constantly being shaped into landforms such as caves‚ arches‚ stacks and stumps through marine erosional processes and wave refraction. The combination of these processes working in conjunction

ABSTRACT The objective of these experiments is to determine specific gravity‚ absorption capacity‚ and fineness modulus of a f ine aggregate sample and to plot a gradation curve for the sample. The scope of the experiment was limited to one aggregate sample only. In determining the SSD and oven-dry weights needed for calculation of specific gravities‚ a conical mold was used to reach an SSD condition and the sample was later dried in an oven. Sieve analysis determined the particle size distribution

‚How many people does it take to drink one bottle of English wine? Four - the victim‚ two to hold his arms and one to pour it down his throat.’ This joke elaborates the common held opinion about the quality of English wine at the present day‚ but this will change as a result of climate change. The difference of climate and weather needs to be understood to comprehend this topic. Weather is defined as ‘The specific condition of the atmosphere at a particular place and time.’ Climate can be defined

Determination of specific heat Capacity of a solid by electrical method Introduction Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies‚ heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius‚ different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the

This article aims to study the applications of chaos theory in Tom Stoppard’s major play‚ Arcadia. Although chaos and chaotic systems mainly belong to the sciences of physics and mathematics‚ the theory of chaos as a postmodern matrix can be discussed in both art and literature. Stoppard’s‚ and other interdisciplinary author’s‚ main source is James Gleick famous book “Chaos: Making a New Science”. Chaos theory is a branch of nonlinear dynamics that have an orderly disordered nature; i.e. it shows
