The Kings burial chamber‚ the Queens burial chamber. The other chamber was beneath the King and Queens chamber and was unfinished. ➢ The burial chamber can be reached by a series of passages including a 9 metre hire gallery. ➢ There are many passages that were made with traps

Physics 1968 was awarded to Luis Alvarez "for his decisive contributions to elementary particle physics‚ in particular the discovery of a large number of resonance states‚ made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Alvarez’s colleagues sometimes called him the "prize wild idea man" because of the huge range of his activities. He did all kinds of research into the atomic nucleus‚ light‚ electrons‚ radar‚ and so forth. In 1943 he was part

However‚ do people really know how they worked and who where needed to let these killing machines function? The answer is no‚ some can still tell how the gas chambers worked‚ but barely anyone knows who

1. Objective The aim of this laboratory experiment is to analyse the rate of heat transfer losses through convection and radiation separately from a cylindrical glass rod suspended in a pressure vessel. The variation of the dimensionless quantities; Nusselt number‚ Prandtl number and Grashof Number‚ with Pressure are to be analysed graphically as well. The experimental graph of log10(Nu) vs log10(Gr.Pr) should be plotted and analysed against the graph of the empirical equations. 2. Introduction:

maintained by throttling the steam through the jets or nozzles. Working of steam jet refrigeration system: - The flash chamber or evaporator is a large vessel and is heavily insulated to avoid the rise in temperature of water due to high ambient temp. It is fitted with perforated pipes for spraying water. The warm water coming out of the refrigerated space is sprayed into the flash water chamber where some of which is converted into vapours after absorbing the latent heat‚ thereby cooling the rest of water
