    Slug Catcher Design Companies

    Thanks big & little inches. y'all are brothers? :) I thought I had replied earlier but I guess it never wen through, but lil inch. I am not seeking a company that has to be in West Virginia. It doesn't matter to me where in the USA the company is located. going "across the pond" thought may...

    Slug Catcher Design Companies

    Thanks for replying littleinch. let me rephrase a couple of sentences which hopefully will minimize some confusion:" We have a slug catcher made by a company which is not working for our operating conditions. The manufacturer for it seems unwilling to help, so we want to have another company...

    Slug Catcher Design Companies

    Anyone have suggestions on a good company for engineering slug catchers? We have a slug catcher made by a company which is not working for our operating conditions. The manufacturer for it seems unwilling to help, so we want to have another company review the design and give modification...

    pump pressure variables

    "I should know by now not to assume ANYTHING in these forums. The seem to be affected by Murphy's_Laws^2 " lol! Or assume that you got incomplete info :( Sorry about that BigInch, but do appreciate your input as always - very insightful. On a related note with regards to the pressure...

    ok. I'm not sure why neither file uploaded..?? trying to upload again...http://files.engineering.com/getfile.aspx?folder=f7758408-c2c8-4e72-b435-e8e0783a788b&file=Pump_Operation_Measurements.xlsx

    pump pressure variables

    Oops. Here is the other file summarizing the measured parameters. I guess I can only load one file per message? Anyway we still have slightly more head than anticipated. Since we can't safely reduce the impeller size any less, we will install either an orifice plate in that 3" branch or open a...

    pump pressure variables

    Johnny, I make no profession to be a "pump guy" & I respect your knowledge in the field. What I shared before was simply what I observed in the field and what I could interpolate from the suppliers pump curve based on field results. I do agree that something is not right. I have attached the...

    pump pressure variables

    Well the 6.75" impeller did not give the expected result. The pressure at the 3" branch was 72 psig. (This is the same location that we took all previous discharge pressures, by the way). Johnny, as Ted suggested I thought increasing the head increases the pump flow. I believe it's a...

    pump pressure variables

    Thanks Dubmac. Based on the dP measured & the manufacturer's curve seems we were getting close to 200 feet of head and over 400 gpm! wow! We're in the process of having the impellers trimmed. The supplier didn't have any in the size needed in stock. Hopefully reducing the impeller diameter...

    pump pressure variables

    I'm sorry, but the diagram does not indicate the expansion tank. There is one in the system & it is vented. So it is not a truly closed loop. I had also contacted the pump manufacturer yesterday & heard back from them today. The problem was exactly as several had suggested - the impeller was...

    pump pressure variables

    Thanks all. I really appreciate the suggestions :) gr2vessels, we could probably live with reduced flow if we go with a smaller impeller. Is there a rule of thumb correlating flow with impeller diameter? or should I just go with the supplier's pump curve? bimr, we have gate valves installed...

    pump pressure variables

    Does anyone have ideas on how to reduce pump outlet pressure? We recently installed a pair of pumps (primary & backup up operation) which are delivering 80 psig pressure where we were expecting about 50-60 psig. I'm not sure why it's building that much pressure, but need to know ways/ideas on...

    Online Source for Equivalent Lengths of Pipe Fittings

    ...on the 6" header plus that individual branch instead of the total area based on the branches (3" & 4"). In short I multiplied my flowrate by [pi*4^2/4]/[(pi*6^2/4)+ (pi*4^2/4)]. That is wrong. Instead it should be: [pi*4^2/4]/[(pi*3^2/4)+ (pi*4^2/4)]. Using the corrected formula I got...

    Online Source for Equivalent Lengths of Pipe Fittings

    katmar (harvey?), I actually tried multiplying the flow by ratio of cross sectional area for each branch, but the sum of the branch flows didn't equal the (total 325gpm) flow. for the 4" branches the flow was ~43 gpm & the 3" branch had 24 gpm flow. Unless I did something wrong? I multiplied...

    Online Source for Equivalent Lengths of Pipe Fittings

    ...3" branch (pipe) reduces to 2" pipe. The other branches remain the same. So for my corrected flows to each branch I did the following: total flow * (branch diameter/sum of branch diameters) so for the 4" branches that gave me: 325 *(4/11) = 118 gpm & fluid velocity of ~3 ft/s for 3" branch...

    Online Source for Equivalent Lengths of Pipe Fittings

    ...a 6" pipe system I get a K value of 4.1 & my Head loss is ~61 feet. That seems a bit high to me. I'm using the formula: HL (headloss) = (0.00259 * K * Q2)/d4 Q=325 gpm. I used 2" pipe for d. Should I have used 6" instead since I already converted the for 6" pipe when I calculated K...

    ...different pipe sizes when I'm ultimately trying to determine the head loss (Hl). should i apply this ratio to the equivalent length formula & then determine K from f*L/D? Or should I determine K from the Crane paper appendix & then apply this beta (ratio coefficient)? hope this makes sense.

    Online Source for Equivalent Lengths of Pipe Fittings

    I've been away on vacation so sorry for the delayed response, but thanks Katmar & others as well. I calculated a Reynolds number of ~6E4 so my flow is in the transition near turbulent zone. So how do I get an equivalent length for reducer? I have 2" x 3" reducers, 6" x 4" reducing tee & 6" x...
