Dear Experts,
Something in centrifugal pump or fan is vague for me so please correct my understanding:
In centrifugal pump or fan the vertical axis is the differential pressure across the pump or fan and horizontal axis is
flow and more flow means low pressure across the pump or fan and vice versa.
By measuring the pressure across the pump the flow can be determined by referring to its curve(by considering the pump or fan speed)
The questions that I don't know their answers so please let me know:
Will increasing the speed of pump or fan cause the inlet pressure to it get decreased?
Suppose there is an exhaust fan and a differential pressure transmitter connected to it's inlet . what happened to the pressure
indicated by the transmitter according to the fan speed change.
Regards,
