Re: [MW:10042] Re: hydro test (static pressure head)

Hi
 
As per paradox law of hydraulics, the pressure directly proportional to elevation
 
So , if there is height diffrence between the pressure gauges, you will definitely will get an difference in readings.
 
You may refere the fundamentals of hydraulics
