Hydraulic Power and Hydraulic Machinery [PDF]

open access: yesNature, 1887
THIS work purports to “record existing experience in this branch of engineering.” It is divided into thirty-five short chapters (not numbered, and therefore not quite easy of reference). Five of these treat of general subjects, and the rest of particular machines or details. Hydraulic Power and Hydraulic Machinery. By H. Robinson, M.I.C.E., &c. Pp. xiv.
