Spray Nozzles 26
Spray Nozzles 26 : Spray Characteristics 5: Capacity: Spray nozzle manufacturers all tabulate capacity based on water. Since the specific gravity of a liquid affects its flow rate, the values must be adjusted using the equation below, where Qw is the water capacity and Spg is the specific gravity of the fluid used resulting the volumetric flow rate of the fluid used Qf. Nozzle capacity varies with spraying pressure. In general, the relationship between capacity and pressure is as follows: where Q1 is the known capacity at pressure P1, and Q2 is the capacity to be determined at pressure P2
