Here is a simple approximation that you could use as a sanity check. It would err on the conservative side so you may slightly oversize...

1. It appears that your discharge is at a higher elevation than the source, so I cannot see how a siphon can form. 2. The friction...

In order to be able to offset the pressure loss in the up-leg against the pressure recovery in the down-leg you have to ensure that the...

The whole question of entrance and exit pressure losses, resistance coefficients and pressure recovery is generally not well covered in...

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 - you have correctly identified the data required for this calculation but you have not got the correct values for that...

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

To the member(s) who voted down the posts by me and pierreick - you are absolutely entitled to disagree with any post here, but it adds...

For the pressures at which you are working, a well designed piping system will have essentially no pressure drop. All the pressure drop...

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...

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...
