Half-black calf over black cloth, gilt lettering stamped on front cover, leather corners (minor chipping & wear head & foot of spine, scuffing to spine, wear to corners), still VG- copy. This manuscript thesis details the testing and evaluation of the newly developed Parsons Steam Turbine, which was invented by Sir Charles Parsons in 1884, and revolutionized engineering across many fields in the Victorian era. His turbine extracted thermal engineering from pressurized steam, allowing a rotating output shaft especially suited for driving electrical generators. In 1897, just four years before this work was researched and published, the Parsons engine was applied to the ship Turbinia, the first ship powered by the very successful enginer. Ehrhart (1874-1941) & Cardullo (1879-1938) were both electrical engineering students at Cornell University. After graudation, Ehrhart became an electrical engineer with expertise in turbines for Westinghouse in Pittsburgh, and by the end of World War I, Ehrhart was a manager of the Elliott Electrical Engineering Company in Edgewood, PA, nice suburb of Pittsburgh. Cardullo became a professor of mechanical engineering, wrote on thermodynamics, and later worked as the chief draftsman of the Pierce-Arrow Motor Car Co., before becoming the head of engineering testing for the Curtiss Aeroplane & Motor Co. in Buffalo, NY.
