Translated from Russian by Natalia DeinekoFirst published 1986Revised from the 1979 Russian editionThis book of problems has been compiled in accordance with the curriculum “Fundamentals of Heat Engineering and Hydraulics” for technicians of industrial and technological specialities. Each chapter contains the basic theoretical concepts, the computational formulas and relations and some typical problems, some of which are solved. Some of the problems and appendices are taken from the literature on the subject. The appendices contain the reference data required to solve the problems. The problems mainly use International System of Units (SI). However, since many of the instruments used in industry are graduated using other systems of units, these units are also used in some problems.Chapters 1, 5, 6 and 11 and sections 7.2, 7.3, 8.1, 8.2, and 8.3 were written by V.G. Erokhin, and the rest of the book by M.G. Makhan’ko.
