It is rated at 500 hp per minuteat 3,000 , with steam at 147 pounds. It is directly coupledto a Siemens & Halske dynamo. A surface condenser driven by anindependent steam engine is used. Part of the water for the con-denser was taken from the city mains and part was pumped elec-trically from the works well. This renders it very difficult to de-termine the power needed for the condensing plant. The unit has. FIG. 2.—ZOELLY STEAM TURBINE. been tested by Prof. Stodola and Director Wagner of the municipalelectric station. They made no attempt to determine the steam con-sumption of the condenser, and the output of the turbine was figuredfrom the current delivered by the generator. The following state-ments concerning the test and its results are condensed from theirreport: The pressure and temperature of the steam were observed in themain in front of the separator, which is close to the turbine. Dur-ing the tests with superheating a thermometer was also placed infront of the throttle valve. The pressure and temperature werealso measured immediately in front of the first diaphragm and thepressure behind the first rotor was observed, from which data acheck on the feed water determinations was obtained. The pressurein the pipe connecting the two halves of the turbine and the pressureand temperature at the entrance to the exhaust main were alsoobserved. The temperature of the cooling water ente
