In an industrial manufacturing plant, 1! standard-type NPT full-cone spray nozzles (Fig. 4-69) are to be used to spray 60°F cooling water. Nozzles are to be placed on a pipe along a 10-ft length. A 30-gal/s flow rate is required. Determine the number of nozzles, specify the type, and estimate the pressure required at the pipe inlet. Would the resulting spray patterns be uniform?
