Class Information
Number: 137/888
Name: Fluid handling > Systems > Multiple inlet with single outlet > Combining by aspiration
Description: System in which a fluid flowing from a first inlet flow line causes or facilitates the flow of a fluid from a second inlet flow line so that the fluids are combined prior to leaving the single outlet or exhaust passage, the fluid flowing from the first inlet flow line serves as the motivating or aspirating fluid while the fluid in the second inlet flow line serves as the aspirated fluid; whereby, the motivating or aspirating fluid imparts energy to the aspirated fluid by the action of entrainment.
