    Pressure on Flat Plate not Matching Hand Calcs

    Thank you for the information. Is there a way to select linear vs non-linear analysis when running a Simulation? I know that if the deflection is over a certain amount a warning notice will pop up asking if I want to enable "large displacement analysis" but I am not aware of any way to manually...

    Pressure on Flat Plate not Matching Hand Calcs

    I have been trying to model a hydrostatic pressure inside a shipping container for some time now and have been having on again, off again luck. Recently it's been off, even the mesh has been finicky. To back up and check my progress I decided to simply load up a flat plate of equivalent...

    PE Seal Question - Location Based

    Thank you for the replies. The item is an industrial application to seal off a low pressure steam leak and is not subject to any building or OSHA standards as far as I know. I would not think there are any local codes that would come into play. The device is mainly to save the client money from...

    Pumps in Series - Total Dynamic Head Question

    Thank you all for the help. I am using the basic formula dP=SW[dZ+Hl) since the velocity stays the same. One question I have tho is on the lower flow runs I am coming up with a negative pressure drop. I.E. the elevation change is greater than the Headlosses. Also for the total head required of...

    Pumps in Series - Total Dynamic Head Question

    Sorry for any confusion. The piping is sloped downhill yes, but there are several areas where the pipe has a "U" in it to go up 20'over a road to allow for trucks to clear and they need to move the gas at a very high rate. Its 36" pipe. MortenA: Thank you for your reply. dH is the major/minor...

    Pumps in Series - Total Dynamic Head Question

    The suction headers are in the ground and the piping runs pretty much level but there are a few places that jump up 20' and go over a road/piping rack and then back down again. Also, gravity will not move any fluid that fast. From point A (Tank Sump) to Point B (Pump Header) its a elevation...

    Pumps in Series - Total Dynamic Head Question

    Hello everyone. New to the forum and after having searched for the subject I haven't really found what I need. The situation is a gasoline transfer project from a large storage tank to an intermediate pump to a large transfer pump that is already in place. I need to determine the discharge head...
