Disclosed is a method of designing an aerosol spray dispensing system. One or more to-be-determined attributes of the spray dispenser system are identified, including properties of a fluid to be dispensed, characteristics of the dispensing mechanism, and performance characteristic values. The identified attributes are determined using equations taking into account relationships among the properties of the fluid to be dispensed, the characteristics of the dispensing mechanism and the performance characteristic values. Once determined, the attributes are used to design the spray dispensing system.
