For a condenser or heat exchanger where the medium operates under negative pressure, at -500 Pa, how should the capacity of the fan or water ring vacuum pump be determined?
When I see this parameter, I know it’s just a made-up number; how can choosing some random value determine which pump to use?……
There’s no need to reply to such stupid questions meant to draw attention – it’s a waste of our time! There are more and more idiots who don’t ask questions and don’t use their brains!
