Guide for Relationship Between Flow Rate And Pressure
The relationship between pressure and flow in the pipeline is proportional. That is, the greater the pressure, the greater the flow rate. The flow rate is equal to the velocity multiplied by the section. For any section of the pipeline, the pressure comes from only one end. That is to say, the direction is one-way.
