Can someone help me calculate the vacuum pressure and/or suction pressure for the following system?
Case 1
1 pump only
Pump capacity = = 4.2m3/min
Hose diameter = 18mm
Case 2
2 Pump connected in series
Pump capacity = = 4.2m3/min
Hose diameter = 18mm
Case 3
2 Pump connected in parallel...
i know that connecting a few pumps in 'series' and 'parallels' yield different results respectvely, in terms of pressure capacity. How and what model (theoretical ref) to explain the result?
