ABSTRACT
The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic nonequilibrium conditions in the ejector motive nozzle. Modifications were made t ....etc

Entrainment Theory



The need for entrainment in parcel theory was pointed out in 1947 by Stommel, who observed that
the differences between temperatures in clouds and ambient temperatures were much smaller than
one would expect based on a non-entraining parcel. These potentially large temperature differences
are easy to see with the parcel model for this class, as well as the ability of entrainment to effectively
reduce the difference between environmental and parcel temperatures.

1. INTRODUCTION
Rocket engines that work much like an automobile engine are being developed at NASA s Marshall Space Flight Center in Huntsville, Ala. Pulse detonation rocket engines offer a lightweight, low-cost alternative for space transportation. Pulse detonation rocket engine technology is being developed for upper stages that boost satellites to higher orbits. The advanced propulsion technology could also be used for lunar and planetary Landers and excursion vehicles that require throttle contr ....etc

CHAPTER 1
Introduction
1.1 Background
Economic reformation and industrial liberalization by Indian government have attracted varied national and multinational companies to invest on major industries like power plant, petroleum refineries, fertilizers and petro-chemicals and metal industries. Most of these industries are located very close to the sea due to a variety of reasons like convenience in transporting raw materials, availability of seawater for desalination, cooling tower and disposal of trade effluents. Both central and stat ....etc

EJECTOR refrigeration cycle of expansion (EERC)

SUMMARY
Expansion cycle ejector refrigeration (EERC) is a variant of the standard vapour compression cycle in what year the ejector is used to restore part of the work that would otherwise be lost in the expansion valve. In initial Testing consortium of poor performance, mainly due to the non-equilibrium thermodynamic conditions causes the ejector nozzle. The changes made to fix the problem and improve the performance of significant were found.

Machine Guns
Introduction
To understand how machine guns work, it helps to know something about firearms in general. Almost any gun is based on one simple concept: You apply explosive pressure behind a projectile to launch it down a barrel. The earliest, and simplest, application of this idea is the cannon.
A cannon is just a metal tube with a closed end and an open end. The closed end has a small fuse hole. To load the cannon, gunpowder (a mixture of charcoal, sulphur and potassium nitrate) is poured ....etc

ABSTRACT

A moving train contains energy, known as kinetic energy, which needs to be removed from the train in order to cause it to stop. The simplest way of doing this is to convert the energy into heat. The conversion is usually done by applying a contact material to the rotating wheels or to discs attached to the axles. The material creates friction and converts the kinetic energy into heat. The wheels slow down and eventually the train stops. The material used for braking is normally in the form of a block or pad.

F1 Cars

INTRODUCTION
Car racing is one of the most technologically advanced sports in the world today. Race Cars are the most sophisticated vehicles that we see in common use. It features exotic, high-speed, open-wheel cars racing all around the world. The racing teams have to create cars that are flexible enough to run under all conditions. This level of diversity makes a season of F1 car racing incredibly exciting. The teams have to completely revise the aerodynamic p ....etc
