The book presents a theory of mechanical efficiency at a level of ideality and generality compatible with the treatment-given to thermal efficiency in classical thermodynamics. This yields broad bearing results concerning the overall cyclic conversion of heat into usable mechanical energy."--BOOK JACKET UR - http://catdir.loc.gov/catdir/toc/ecip0617/2006022394.html UR - http://catdir.loc.gov/catdir/enhancements/fy0665/2006022394-d.html UR - http://catdir.loc.gov/catdir/enhancements/fy0806/2006022394-b.html ER -
