    Help w/Pump Sizing for multiple branches

    HEC: If I use the procedure you explained in you last post, how do I account for any liquid static head in each of the sections of the system?

    BigInch: was that a link to a site? I couldn't click on it.

    Help w/Pump Sizing for multiple branches

    I've been away from the forum because I've been sick with the flu. I'm going to try HEC's method and see what I come up with.

    Help w/Pump Sizing for multiple branches

    I think that's much clear. Is there a way to post a jpg picture in a post so I can show you what the piping arrangement really looks like?

    Help w/Pump Sizing for multiple branches

    No, it's still 35 gpm. If your read Pleckner's last post, he stated that I should look at frictional loss at the first branch using the total flow (35gpm). Then, look at the frictional loss at the first branch using the branch flow (15gpm). At the end of my post, I was just list the 3 different...

    Help w/Pump Sizing for multiple branches

    Pleckner: I follow the first paragraph of your response. I have three branches, but only two are used at the same time. It's your second paragraph that's got me confused. Are you saying that I should calculate the frictional losses of the filter branch at 35gpm and then calculate the frictional...

    Help w/Pump Sizing for multiple branches

    HEC: I did look at each "leg" of the piping. As it turns out the "leg" with the filter, 15 gpm resulted in a 7 ft of head. The "leg" that goes to the aquarium, 20 gpm resulted in 14ft of head. So, even though I'm looking for only 15 gpm to the filter and 20 gpm to the display aquarium, you're...

    Help w/Pump Sizing for multiple branches

    I understand that I have to account for all the friction losses in the piping. I wasn't sure if I had to look at each branch independently and come up with a TDH for each branch then sum them up for the total head.

    Help w/Pump Sizing for multiple branches

    I'm trying to size a pump for use in an aquarium system. The pump flow will be 2100 gph (35 gpm). The pump suction will come from a sump. The discharge of the pump will have three branches. One branch will be to a filter at 900 gph (15 gpm) and the other two branches will return water to the...

    Siesmic Zone 8

    Can anyone tell me if a siesmic zone 8 exists in the United States? A co-worker insists that one exists but I don't think so. If one exists, can someone point me in the direction to obtain some information? Thank you

    U.S. Siesmic Zones

    Has anyone heard of a siesmic zone 8 in the United States? a co-worker insists there is a zone 8 but I don't think so. If one does exist, can someone provide me with some information? Thank you.

    Fractions in text and dimension text.

    I'm using a new Architectural Font on my drawings. I have the olique angle set to 15 deg. The problem I'm having is when I type in a whole number with fraction as text, the fractional portion of the text is spaced at a nice distance away from the whole number and the slash between numerator and...

    AutoCAD Linetypes for P&ID's

    I'm trying to find AutoCAD linetypes for the various type of lines used on Piping and Instrument Diagrams. Lines such as pneumatic, hydraulic, etc. I'm also trying to develop a custom linetype like this: O O O O O O to repesent client supplied piping. Any help would be appreciated. Thanks
