One is impressed with two distinguishing features of the tur-bines steam efficiency, namely:—that it seems to vary but littleover wide ranges of load, and. further, that the size of the unitlias comparatively little bearing. It follows, then, that if goodresults are possible at all. they are neither restricted to the largerplants nor to the requirement of steady load. Fig. 4 illustrates this. Herein are given the results of testson a 40il-kw. turbine, made at the builders works before ship-ment, the machine having Since been in daily operation some. \M AT WORKS OF WE8TINOHOUSE AI« lt;i OUB 100-KW.
