Synopsis

Excerpt from Flow and Measurement of Air and Gases

For those who are ready to accept any formula without caring how it is arrived at or what values of the constants are included, this book will not perhaps be of much interest, as it is largely concerned with those very points. But for those who want to know upon what foundations graphs and formulae are based it should be of value.

As regards subject-matter Chapters II. And III. Deal with the flow in pipes; Chapters IV. To VII. Deal chiefly with pneumatic tube problems Chapters VIII. To X. Deal with the measurement of air and gas, about which little information is given in books on air compressors, and include a description of the recent development of hot-wire anemometers Chapters XI. To XIV. Deal shortly with some subsidiary questions relating to air flow.

Some of the graphs are plotted on logarithmically ruled paper, which deserves to be much better known in this country. A few abaci are included, these being a very convenient form of graphical chart.

The metric symbols cm, kg, m are printed without a full stop, as is customary in French and German journals.

The numbering of figures, equations, and tables is done consecutively for each chapter, not for the book as a whole. Use is made of the to differentiate between the chapter number and figure number, viz. 31, etc.

I shall be glad if attention is drawn to any mistakes and errors which may have crept into the formulae and tables in this connection it may be stated that the constants in the formulae have only been calculated upon a slide rule and may be 5 per cent. Out. Such inaccuracy is immaterial in ordinary air and gas work, as the varying conditions of the atmosphere cause the specific volume of air to vary much more than 5 per cent. From day to day, or even from hour to hour.
