Determination of suspension flow rate
Thread Content
The suspension is pumped to another tank; how should the pipe diameters at the pump’s inlet and outlet be determined? If the flow rate is too high, the pressure drop in the pipes will be significant, while if the flow rate is too low, the suspended particles may settle. I wonder if anyone has experience with similar designs and could share it
Usually, a bypass pipe is added at the lowest point of the pipeline to allow air to pass through; forced blowing is used when sediment builds up.
Today I went through the handbook on chemical process design; the section on liquid-solid phase material transfer mentioned these issues. However, the calculations are quite complex. Is there anyone with similar experience who can share how such calculations are carried out?
The pipeline leading to the pump for the suspension should be larger; the calculated value is based on a flow rate of 0.5 m.
Flow rate of 1.2 – 2.5 m/s. Excessively high flow rates can cause wear on the pipes.
