Development Using Impulse Wheels in Silt-Laden WaterOF Salt River Project in ArizonaThe section shown in Fig. 69 is through the Cross Cut station of theSalt River Project near Phoenix, Arizona. The station has a rating of5,250 kva. Special impulse water wheels were used on account of the factthat the water held a considerable quantity of silt in suspension and de-posited a troublesome precipitate on iron and steel. These wheels are of aPelton-Doble tangential design furnished by the Pelton Water Wheel LOW, MEDIUM AND HIGH HEAD DEVELOPMENTS 119 Company of San Francisco, each rated at 1000 hp. The unit consists of avertical shaft with six nozzles set equidistant about the periphery of therunner. By changing the number of nozzles in use a practically straightline efficiency curve is obtained regardless of the amount of water passing. 67SK^/J. 6ENER/IT0R£5 Cycles 11,000 Vo/fstK- — 13-3%
