Pneumatic fill rates and calcs
From: 
"Ttail" <ttail@internode.on.net>
      
      
      To the Pneumatic Genii out there. Trying to do some numbers using Paint ball bottle
      to refill the main CJ 12L tank.
      
      2L Paint Ball bottle at 4500PSI (310) bar.
      
      Using P1V1=P2V2 if I have an empty main 12 Litre tank then the calcs say I should
      get 50 bar refill into the main system. However that assumes a complete transfer
      from one bottle to the other. In reality the transfer will stop when pressures
      in each bottle are equal ..... so how to calculate the residual pressure
      in each bottle ?
      
      Then taking it a step further. Say I have 20 Bar in the main system what will my
      310Bar 2l paint ball bottle then get ?
