I have a problem designing and understanding Wet and Dry vacuum cleaners. I understand some of the basics behind pressure however things I need to know is:
- what pressure/ velocity is needed to suck up water?
- how to calculate the pressure and velocity generated by the fan? (some examples of the impact different fans have would be great)
- What low pressure needs to be made for the water to drop and not get sucked up by the fan?
- Does the height of the fan have any impact?
