multistage ejector systems will simplify your task of designing vacuum-producing equipment for any pressure. F. DUNCAN BERKELEY GRAHAM MANUFACTURING CO.‚ INC.‚ BATAVIA‚ N.Y. B ecause of overlapping performance‚ it’s often a lengthy problem to arrive at the most economical design of an ejector. In practically every new application of high vacuum‚ we find it necessary to investigate thoroughly the many available means of producing vacuum to reduce equipment and operating costs to a practical and

Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The

between atmospheric pressure and the pressure of whatever they are attached to. Vacuum gauges are differential gauges that measure how far BELOW atmospheric pressure the pressure is in a vessel or pipe. Gauges that measure "gauge pressure" are just differential gauges that are calibrated to measure zero at atmospheric pressure. Absolute pressure gauges would only read "zero" if they were attached to an absolute vacuum. A common type of absolute pressure gauge is a barometer. Strictly speaking‚ a mercury

Nowadays‚ a Pitot tube would be of use as a speedometer on aeroplanes. It is also found useful in industries where velocity measurements are required‚ where an anemometer may not be the most efficient instrument to use. There are three types of pitot tubes: Pitot tubes‚ Static tubes‚ and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°‚ with an open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant
