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

The Advantages and Disadvantages of Electric Cars Introduction to Electric Cars An electric car is a vehicle which is driven by electric engines. The engines use electrical energy which is usually stored in batteries. Electric car is a variation of electric vehicle (EV). EV speaks of any vehicles which are propelled by electric engines. “Electric car” is a general term for high-speed vehicles which are powered by electricity. In the United States‚ low-speed vehicles which are powered by electricity

Electric cars vs the gas oh line cars In the next ten years what the average American drives will be very different than today. Electric cars may phase out gasoline (Gasoline is also known as petrol) in the next couple of decade. Electric cars produce no tailpipe emissions and are much cheaper to fill up than the more common gasoline vehicles. Switching to electric cars will have more benefits than drawbacks in comparison to other fuels such as petrol and diesel. In order to switch to electric

The two most important issues that Lincoln Electric is faced with are as follows. First‚ the inability to meet customer demand because of the shortages in supply creates opportunities for competing firms to enter the industry. What resources and capabilities does Lincoln Electric have that can mitigate this threat of entry. Second‚ the emphasis put on the monetary incentive plan leaves the company vulnerable in economic hardships. How can Lincoln Electric continue to encourage competition and quality

Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

Introduction and Experimental Goal: An electric field surrounds all electrically charged particles. With electric fields‚ one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”‚ the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces‚ changes in motion‚ changes in current flow‚ etc. By using conductive

issue of electric car has been arising nowadays. But many of us never really find a true example of the uses of electric cars in everyday life. From the article "Electrical Engineering"‚ an Australian built his own electric car from a second hand Porsche. The article proves that having a private electric cars is no longer a dream. But do all people know the good things and the bad things about having a private electric car? Now‚ what electric vehicles really are? Simply put‚ electric vehicles
