    Is it possible to avoid the high point by following the contours from the source to the destination? If you bring the highest point...

    I agree with LittleInch that you have an error in your Bernoulli calculation. Assuming that you are pumping something similar to water...

    @Javier Sanchez - You can use a similar technique to the way you would match the curves for a centrifugal pump system. The difference is...

    As pointed out by Pierreick and Snickster, the up and down voting system is a bit confusing if you have not seen it on other forums...

    @Asisraja D - Your general procedure makes sense, but there are a few items I believe you have got wrong. Bottled nitrogen is unlikely...

    katmar replied to the thread Pressure in vacuum line.
    For the pressures at which you are working, a well designed piping system will have essentially no pressure drop. All the pressure drop...

    katmar replied to the thread Pipe inlet design.
    Unless there is a dip pipe inside the tank that is connected to the outlet piping the loop on the outlet is not a siphon. It is just a...

    katmar replied to the thread Pipe inlet design.
    I think that LittleInch nailed it, even though auto-copulation added some confusion. The loop will not help with condensate collection...

    What is the design pressure for the main tank? How did you select 7" as the outlet line size from the seal pot? Where does this outlet...
