Abstract:
A method for determining an appropriate fluid flow for unloading materials from a hopper via a convey line that runs below the hopper, the convey line having a first end and a discharge end and a valve positioned between the hopper and the convey line, comprising the steps of:a. closing the valve between the convey line and the hopper; b. installing a plate onto the discharge end of the convey line so that the discharge end sealingly engages the plate, the plate defining an orifice therethrough that is in communication with the convey line when the plate is installed onto the discharge end; c. connecting a blower to the first end of the convey line, the blower capable of operating at different speeds, each speed resulting in the blower discharging the fluid at a predetermined pressure and velocity; d. operating the blower to obtain a desired pressure within the convey line intermediate the first and discharge ends thereof; and e. recording the speed of the blower in the operating step when the desired pressure has been obtained.
