Excerpt from The Mechanics of Pumping Machinery: A Text-Book for Technical Schools and a Guide for Practical Engineers The volume herewith presented might be introduced in the same words as its recent predecessor on The Mechanics of Hoisting Machinery. It is a translation of a portion of Professor Herrmann's revised edition of Weisbach's work on Engineering Mechanics, which has not before appeared in English. Moreover, it is destined mainly to serve as a text book for the advanced courses in the Mechanics of Machinery, though it may also prove of value to the practical engineer.
