Do not need to get too detailed, but I need to know the rate of change of the pressure in a vessel(gas digester) caused by a compressor sucking the gas (methane) out. Starting pressures are 0-10 inches.
1. 1000 ft 20" gas (methane) pipeline flowing 1250 scfm @ 5-10" W.C.
2. Valve closes
3. How high will the pressure "spike" ?
4. 2 - 8 Bio Gas digesters = huge volume in dome.
