is the third fastest stroke competitively‚ originated from an old english style of swimming backstrokeand has developed over the years and has evolved into an alternating and more effective action. This action givesthe backstroke less resistance with a continuous propulsion. The speed of the backstroke is limited by the restrictiverange of movement of the shoulders as well as the ability/inability to use the power in the chest muscles to thebest desired effect by the roll of the body which will be

MAGNETIC LEVITATION AND TRAINS BY: MANISH KUMAR 2K12/EE/075 Delhi Technological University INTRODUCTION MAGLEV = MAGNETIC + LEVITATION Magnetic means “based on magnets” Levitation means “to rise and float in air” Maglev is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels that the conventional trains use. Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and

or dye-based but the print head is produced usually at less cost than other ink jet technologies. Second type of ink jet printers are piezoelectric ink jets‚ which uses a piezoelectric crystal in each nozzle instead of a heating element. Piezoelectricity is the ability of crystals to generate a voltage in response to applied mechanical stress. When current is applied‚ the crystal changes shape or size‚ forcing a droplet of ink from the nozzle. Piezoelectric ink jet allows a wider variety of inks

expected from an application of the momentum principle to the control volume that surrounds the water jet. Theoretical consideration Mechanical work can be produced by using pressure of moving fluid at high velocity. As an example jet of water from nozzle can produce force when it strikes a plane of the surface of plate. If the jet of water impinges on the flat plate which

CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Transport along with communication‚ forms the core of day to day life of modern world. Conventional rail transport through wide spread is now being considered inefficient in terms of fuel consumption and is time consuming. A genuine replacement for railways which is not only fuel efficient but also highly comfortable and can attain unimaginable velocities of around 450 – 500kms/hr are Maglev Trains whose idea was given by Robert Goddard‚ an American

and finally exhausted out of the engine. This creates thrust in the engine and causes the vehicle to propel forward or backwards. These steps are carried out by the five major engine components: the fan‚ compressor‚ combustor‚ turbine‚ and exhaust nozzle. The compressor and turbine contain high and low pressures. These components are shown in Figure 1. In Figure 2‚ it shows all the 5 main components of the engine starting from 1 and then towards the end to 5.

process. Advantages and Disadvantages Because the tool does not contact the work piece‚ its advantage over conventional machining is that there is no need to use expensive alloys to make the tool tougher than the work piece. There is less tool wear in ECM‚ and less heat and stress are produced in processing that could damage the part. Fewer passes are typically needed‚ and the tool can be repeatedly used. Disadvantages are the high tooling costs of ECM‚ and that up to 40‚000 amps of current must

The paper presents two types of fine bubble generators with the same number of nozzles‚ but differently placed. These two types of generators will be used in order to experimentally research the efficiency of the water oxygenation process; an experimental setup was designed and built; the setup is endowed with modern instruments: oxygen
