Determining Discharge Rates of Particulate Solids | AIChE

Flooding of powders can be prevented if the fundamental causes, such as insufficient deaeration or aeration at the outlet due to a negative pressure gradient, are properly addressed. As our understanding of bulk solids behavior has evolved, so has our ability to appreciate the myriad factors influencing the discharge rate.

Pressure Loss Calculations

This pressure difference can be positive or negative depending on the reference point (inlet higher vertically than outlet, or outlet higher than inlet). Under ALL circumstances , irrespective of what sign convention is used, the contribution of the hydrostatic pressure calculation must be such that it tends to make the pressure at the vertically-lower end higher than that at the upper end.

Precision Pressure Controls | Pressure Regulators & Valves …

The output pressure of the pump is set using a back pressure regulator. Once the pressure is set, the flow rate to the process is established. The back pressure regulator (BPR) will isolate any changes that occur in the downstream system by making adjustments in order to keep its inlet pressure (the pump’s output pressure) at the target setpoint.

Vertical axis wind turbine technology continues to improve

1.3.3 A good vertical axis wind mill has to remain stable when it is spinning it. If not, the turbine will “shake its head” when the rotor is turning. That will reduce the turbine’s life and cause other problems such as noise and mechanical wear. So the best solution is
