Discussion Overview

The discussion revolves around calculating the power required for a device referred to as a "water compressor," with participants questioning the terminology and suggesting alternatives such as a water pump or pressure washer. The scope includes theoretical and practical considerations related to fluid mechanics and efficiency in pumping systems.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks a formula for calculating the power needed for a water compressor.
  • Another participant points out that water is largely incompressible and questions whether the term "water compressor" is appropriate, suggesting it may refer to a water pump instead.
  • A participant mentions that power can be calculated by multiplying pressure and flow rate, while also noting the importance of accounting for efficiency (suggesting 75% efficiency) and ensuring correct units.
  • There is a suggestion that the device in question could be a pressure washer, indicating a potential misunderstanding of the original term used.

Areas of Agreement / Disagreement

Participants generally agree that the term "water compressor" may not be accurate, with multiple competing views on the correct terminology and the appropriate calculations for power requirements remaining unresolved.

Contextual Notes

There are limitations regarding the assumptions about the device's function, the definitions of terms used, and the efficiency considerations that may vary based on specific applications.

Hi all,

I am involve in a group assignment where a water compressor will be used to produce high pressured water.

I would like to know if there a formula to calculate the amount of power needed to operate the water compressor.

Thanks

Welcome to PF.

I've never heard of a "water compressor". Water is largely incompressible. Do you mean water pump? Multiplying pressure and flow rate gives you power - and figure 75% efficiency (and make sure your units are right!).

Hi russ-watters

Thanks for the reply.

What you have said makes sense. A pump should provide an increase in water pressure.

Thanks for the reminder.
