Compressor with a displacement of 10 meter cube hour

AI Thread Summary
A compressor with a displacement of 10 cubic meters per hour operates at a pressure of 10 bar, meaning it displaces 10 cubic meters of air per hour, not 100. The confusion arises from the pressure, but the actual flow rate remains 10m3/h. When the gas is collected and expanded to standard temperature and pressure (STP), it will still measure 10 cubic meters, not 100. The displacement rate is defined by the compressor's capacity, which does not change with pressure. Thus, the compressor's output remains consistent at 10m3/h regardless of pressure conditions.

]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.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
