摘要：
The present inventors have recognized that a pressure gradient or differentialin aproduct distribution line for conveying granular particulate material, such asseed orfertilizer, in an air flow to an agricultural field consistently decreases asair speed(velocity) in the product distribution line decreases until a critical airspeed is reached.Below the critical air speed, the particulate material may become susceptibleto fallingout of the air flow to potentially cause a blockage in the system.Accordingly, a controlsystem can implement a process for efficiently determining an optimumoperatingvelocity for an air flow that is above the critical air speed yet below amaximum air speedassociated with inefficient operation. In one aspect, the optimum operatingvelocity canbe stored as a value corresponding, for example, to the type of particulatematerial and/orrate at which the particulate material is metered for subsequent use.
