Abstract
The Bureau of Mines developed methods to determine operation conditions of spray systems. The plot of water pressure, p, against discharge flowrate, q, produces pq diagrams for the water supply and spray nozzles. Pressure loss in the connecting line can be included in the nozzle curve. The intersecting point between the supply and nozzle curves gives the operating condition of the spray system. The reported methods can be used for the prediction of the nozzle performance of given water supply systems. In conjunction with results of earlier investigations, the present methods can be used to design an optimized plumbing spray system for a given water supply for improved dust suppression. The pq performance of a typical water system in a continuous mining machine is discussed. The report also discusses application of the methods to pneumatic spray systems.
