Pump head and flow rate relation

Click For Summary
SUMMARY

The discussion centers on the relationship between pump head and flow rate, emphasizing that as flow rate increases, pump head decreases according to the pump characteristic curve. The pump affinity laws are crucial for understanding how changes in RPM affect both head and flow rate. Additionally, it is established that reducing pressure resistance in the system can lead to an increase in flow rate while maintaining a constant RPM. This relationship is vital for optimizing pump performance in various applications.

PREREQUISITES
  • Understanding of pump characteristic curves
  • Familiarity with pump affinity laws
  • Knowledge of pressure resistance in fluid systems
  • Basic concepts of RPM and its impact on pump performance
NEXT STEPS
  • Research the specific equations derived from pump affinity laws
  • Explore methods to reduce pressure resistance in pumping systems
  • Study the impact of varying RPM on pump efficiency
  • Investigate different types of pumps and their characteristic curves
USEFUL FOR

Engineers, fluid dynamics specialists, and anyone involved in pump system design and optimization will benefit from this discussion.

i need some help becoase i become confused
according to pump characteristic curve if the flow rate increased the head will decreased
the question is how i can increase the flow rate and what is the relation of RPM with head and flow rate

By combining the first and second equations, you get an equation that tells you that by lowering the pressure resistance in the system, you'll get an increase in flow.
