Compressor with a displacement of 10 meter cube hour

Click For Summary

Discussion Overview

The discussion revolves around the displacement of a compressor rated at 10 cubic meters per hour and its relationship to gas pressure and volume under different conditions. Participants explore concepts related to flow rates, gas expansion, and standard temperature and pressure (STP) conditions.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • Marco questions whether a compressor with a displacement of 10 cubic meters per hour at 10 bar pressure would result in a displacement of 100 cubic meters per hour.
  • Another participant asserts that the displacement refers to the flow rate, clarifying that the compressor displaces 10 cubic meters of air per hour at 10 bar pressure.
  • Marco proposes that if the gas is collected and expanded to STP conditions after one hour, the volume would be 100 cubic meters.
  • A subsequent reply counters this by stating that the compressor can only output the amount it takes in, which is 10 cubic meters.

Areas of Agreement / Disagreement

Participants express disagreement regarding the relationship between pressure, displacement, and volume at STP, with no consensus reached on the implications of gas expansion and the compressor's output.

Contextual Notes

The discussion does not clarify the assumptions regarding gas behavior under compression and expansion, nor does it resolve the implications of pressure on volume displacement.

]Hi Guys

Can you help me with this :

If a compressor with a displacement of 10 meter cube hour is displacing gas with a pressure of 10 bar, it is displacing 100 meter cube hour ??
(10 meter cube x 10 bar)

No, the displacement of the compressor is the flow rate.

This compressor pumps 10 cubic metres of air per hour at 10 bar pressure.

It displaces 10m3/h of air.
 


But if after 1 hour I collect and expand and cool the gas to the STP value (1 atm 0 deg c) the volume will be 100 meter cube ??

No, it will be 10m3.

If it only takes 10m3 in over an hour, it can only put that amount out.
