[Stoves] Pressure calculations

[Frank Shields]

Stovers,

 

Hope I am doing this right by adding an attachment and that the file is not
too big and I get into trouble –like last time. 

 

Container C is filled with an anaerobic mess that releases gas under
pressure. Tubing (~ ¼” dia) coils up into container A.

Container B is filled with water and opening of container A goes in about an
inch. Over flow water from A goes into a catch basin under B. 

 

I can measure the volume of gas captured in A by a calibration on the side
of the clear container or the volume of water captured in the catch basin.
If the type of gas is important I can add NaOH to the water in A to
eliminate the CO2 leaving only methane. But prefer not to. I can add a
pressure/vacuum gauge to the top of A  if needed. The methane coming out of
C is produced with pressure but I think there is no pressure as the 1/4”
tubing is open going into A. Is there a back pressure from the water in A on
the gas coming out of C? Does the height of C relative to A (top or bottom)
have any bearings on the set up?

 

Thanks

Frank

Stovers;

 

Producing methane to use in a burner I am having problems with some pressure
calculations and hope someone can help.

 


Frank, 
  A picture is worth a thousand words here. 

I think I see what you want, and Andrew is going the right way, but I'd like
to see a sketch ?
