The curves given in Fig. 189 were plotted to show graphi-cally the steam consumption of 300, 500, and 1000 kilowattWestinghouse-Parsons turbines with varying loads.* Data ofthe tests from which these curves were drawn, as well as of atest of a 3000-kilowatt turbine are given in the following tests were reported by J. R. Bibbins in 1906 and 1907. * The numbers marked on the curves to indicate the vacuum represent theactual readings taken in the test and are not referred to a standard (30 inches)barometer. 360 THE STEAM TURBINE. o .5^| T) 3 O a> o « <U fa ii a. °P1 oc o o £ 1 u «4H ^ 300-KILOWATT TURBINE (3600 ).
