Pump And Formula for calculations - Need Help Please

Click For Summary

Discussion Overview

The discussion revolves around calculating pump requirements and the full hydraulic system for a mechanical setup. Participants explore how to determine pump pressure, head loss, and the relationship between flow rates and pump selection.

Discussion Character

  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant shares a diagram of a mechanical system and seeks assistance in calculating the necessary pump and hydraulic system parameters.
  • Another participant suggests that pump pressure can be derived from the pump curve and emphasizes that required head or pressure is contingent on the system and flow requirements.
  • A different participant notes the importance of understanding the piping system's head loss, stating that the piping and flow rate will influence pump selection, and clarifies that pumps produce flow rather than pressure.
  • Resources for pressure drop calculations and pump information are provided by another participant, who encourages the original poster to provide more specific details for better assistance.
  • Additional resources, including tutorials and calculators, are recommended by another participant to aid in the calculations.

Areas of Agreement / Disagreement

Participants generally agree on the importance of understanding the relationship between flow, pressure, and the piping system in pump selection. However, there are no explicit resolutions or consensus on specific calculations or methodologies.

Contextual Notes

Participants mention the need for specifics regarding the system to provide more tailored advice, indicating that assumptions about the system's configuration and requirements are necessary for accurate calculations.

You will get the pump pressure from the pump curve and knowing the flow. If you are looking for required head or pressure, then it will totally depend on the system and the required flow.
 
You have to start with your system. You have to know what your piping system will provide in terms of head loss. Your piping and flow rate will dictate the pump selection. Pumps do not produce pressure, they produce flow. Your piping system creates the pressure as a result of resistance to the flow.
