ink droplets onto the paper through the nozzle. Most inkjet manufacturers use this technology in consumer inkjet printers. Piezoelectric inkjet technology is used on all Epson printers and industrial inkjet printers. Instead of using heating element‚ these printers use a piezoelectric crystal in each nozzle. The piezoelectric crystal changes shape and size based on the electric current received‚ and forces tiny droplets of ink onto the paper from the nozzle. Thermal inkjet printers use aqueous

Sided Linear Induction Motor using Stream Function approach Abstract-This paper presents the analysis of longitudinal end effects in a single sided linear induction motor leading to the calculation of fields and currents in the rotor sheet and propulsion and levitation forces. Such problem can be tackled by vector potential or stream function approach. The present paper adopts the second approach. A second order partial differential equation has been formulated for calculation of stream function

A REVIEW PAPER ON MINE FIRE IN INDIA INTRODUCTION The problem of mine fire is as old as the history of the mine. The fires in coal mines are posing great hazard due to its increasing trend in the world and much more so in our country while mining of thick and thin seams under difficult geo-mining conditions. Due to fires in underground as well as surface mines‚ not only a considerable amount of resources is lost‚ but the entire mine environment is badly affected. So long as the fires are restricted

When it came to that famous shower scene‚ Hitchcock not only approved of every little detail in the scenefrom toilet to shower nozzlebut he demonstrated every move the killer and victim were to make. The director even showed Perkins exactly how he was to wrap the body in the shower curtain. Ironically‚ Perkins was not present for the filming of Leigh’s murder. He later commented:

First Law of Thermodynamics The first law of thermodynamics states that the energy cannot be created nor destroyed it can only be changed from one form to another. Another name for this law is the law of conservation of energy. This means that the total energy of a system plus its surroundings is constant and does not change. Energy can‚ however‚ be transferred in or out of the system and to or from the surroundings through work or heat. Conservation of Energy Energy may be defined as the

Ms Sanghamitra‚ R&D Refractory Department from TATA STEEL‚ Jamshedpur‚ gave a talk on “STEEL MAKING REFRACTORY”‚ on 12th September 2012 at 11:00 AM at Ceramic Engineering department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

`Jump to: navigation‚ search A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material. The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands‚ crushed rock‚ clays‚ granite‚ feldspars‚ coal‚ soil‚ a wide range of manufactured

answered by the Meteor. The missile’s ramjet propulsion system gives Meteor its high speed performance and the energy to defeat fast‚ manoeuvring targets at long range. Meteor is equipped with both a proximity and impact fuse to ensure total target destruction in all circumstances. The missile trajectory is controlled aerodynamically using four rear-mounted fins. Meteor’s control principles are intended to allow high turn rates while maintaining intake and propulsion performance. MBDA Meteor is capable of

Product Development models The task of the project is to improve the Novenco fire fighting system by designing a developed version without the problem of clogging. There have been made two alternative systems which both can eliminate the problem. To choose between the two alternatives I have made a preliminary plan for both cases. The plan consists of the best possible team for developing the new Novenco FF and a plan for how the project will progress. This will be a way to work together and structure

This type of Engineer studies the necessary physics for designing aircrafts that will fly; they are involved primarily in designing aircraft and propulsion systems and in studying the aerodynamic performance of aircraft and construction materials. These engineers design aircraft structural components‚ decide and plan the engine propulsion design based upon the aircraft power requirements‚ also they request prototype versions of new designs for testing in laboratories prior to flights.
