PERIPHERAL SPEED

A general idea may be gathered of the intense speed of the rotor, if one can visualize a peripheral speed of 60,000 feet per minute, which is the normal running "time. In other words the tip of each blade as it whirls its way through the mime of stationary blades attached to the inner casing races through space at a rate of no less than 11 miles per minute. A monkey wrench tossed into their midst, would be cut into particles of mince meat, before one could think. Every blade as it left the shaft burst into space at. a speed of half that, probably not over five milles to the minute. The 150 %. piece of what is now scrap iron had the initial impetus of that velocity, but fortunately both it and the smaller pieces were restrained by their attachment bases or they would have caused catastrophe over a great radius; A general conception of the size of the turbine and_ its adjuncts may be obtained from the floor space of the platform upon which it rested. It is between 60 ft. and 70 ft. in length and 20 ft. to 25 ft. wide. The condensing area of the 30,000 or more pipes which turn the steam to water before being returned to the boiler, may be conservatively placed at 50,000 square feet and they are capable of returning to the Hoilers more than 2,000,000 gallons of water each hour the plant is in operation.
