Excerpt from The Flow of Gases and Proportioning Gas Mains: Explanatory of Four Diagrams for Solving at a Glance the Various Problems Involved in Proportioning Gas Mains and Services, to Suit the Varying Conditions of Diameter, Length, Pressure, Specific Gravity, and DischargeBarlow's tables - which are simply tabulated results derived from the applica tion of Dr. Pole's well-known formula to several examples - are very limited in range, and are scarcely reliable for pipes of small diameter. With a view, there fore, to correcting inaccuracies, and displaying on a much more comprehensive scale the several problems relating to the passage of gas through pipes, I have prepared the present work and the accompanying diagrams.The diagrams may be termed straight-lined diagrams, as no complicated curves are employed. Hence, it is very easy to plot intermediate results, when such cases arise, or even to extend the diagrams if required. As now presented, all cases - from 1 inch diameter up to 60 inches diameter, from 10 yards to 20 miles in length from 1 tenth to 100 tenths pressure, from 4 to °7 specific gravity and/from 5 cubic feet to cubic feet discharge per hour - are dealt with. Hence, by simple inspection of these diagrams, a large number of problems may be solved.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
