Relationship between outlet pressure and flow rate of a centrifugal compressor

Is the device operating under overload?
The greater the flow rate, the lower the outlet pressure. The outlet pressure generally does not exceed the design value; it is recommended that the owner verify this, as too high a backpressure may cause surging.
There are many reasons for overpressure at the compressor outlet. Many cases are due to the inlet pressure exceeding the design value.

This indicates that the outlet pressure decreases as the flow rate increases. It is possible that the system will not become overloaded. The operating parameters may deviate from the set values in order to achieve a practical pressure balance. Moreover, the flow rate and pressure cannot both be at their set values simultaneously.
