Principle of steam jet refrigeration system: - The boiling point of a liquid changes with change in external pressure. In normal conditions‚ pressure exerted on the surface of a liquid is the atmospheric pressure. If this atmospheric pressure is reduced on the surface of a liquid‚ by some means‚ then the liquid will start boiling at lower temperature‚ because of reduced pressure. This basic principal of boiling of liquid at lower temperature by reducing the pressure on its surface is used in steam jet refrigeration

This is a Newspaper on Steam engines. The Watt steam engine (alternatively known as the Boulton and Watt steam engine) was the first type of steam engine to make use of steam the new design replaced Newcomen engines in areas where coal was expensive‚ and then went on to be used in the place of most natural power sources such as wind and water. A Scottish instrument maker‚ James Watt‚ was given the job in 1763 of repairing a model Newcomen engine for the University of Glasgow‚ and noted how inefficient

Fractional Distillation of an Ethanol- water Mixture Abstract The purpose of this experiment is to understand the process of distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol

Distillation is a process in which compounds that are in the same solution become separated by their boiling points. For this to occur‚ a heterogeneous mixture has to be placed into a distiller‚ in this experiment a solution of 1:1 water and methanol was distilled. When distilling substances there are various methods of distillation that can be used. In this lab‚ simple and fractional distillation was used. The simple distiller is composed of a 100ml round bottom flask that is attached to: a

The Steam Turbine‚ Part I The Steam Turbine by Sir CHARLES A. PARSONS‚ K.C.B. Best viewed with window no wider than the above line. THE STEAM TURBINE In modern times the progress of science has been phenomenally rapid. The old methods of research have given place to new. The almost infinite complexity of things has been recognized and methods‚ based on a co-ordination of data derived from accurate observation and tabulation of facts‚ have proved most successful in unravelling the secrets of

Report Simple and Fractional Distillation Unknown # 2 Purpose In this experiment we aim to demonstrate that we can separate two volatile compounds from a mixture due to the different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation‚ which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Procedures The experiment

STEAM TURBINES A steam turbine is a prime mover which converts heat energy into mechanical energy. In a conventional steam turbines cycle‚ water is used as the working fluid. The water is heated in a boiler by burning fuel. It evaporates into steam which is expanded in a turbine where mechanical power is generated. The steam generated is of high temperature and high pressure. The temperature is often in the 450 to 540 degrees centigrade range. The pressure ranges between 60 and 120 bar. The
