Okay, so our head engineer just got fired, and one of my big accounts has a question, and **** all if I know how to answer it.

I have a customer that has a 1" line and needs to pump 300' of vertical. What PSI is needed to be able to over come the head of water? Any feedback would be appreciated.

okay so I did some snooping on the internet and it appears that 1 PSI is equal to 2.31 vertical feet of water. Therefore only 700 PSI is needed to overcome a 300' length, which is well within the 1500 PSI limit of the pump I'm selling him.

However, do I need to account for friction in the 1" pipe?

Basic questions:


-flow rate of fluid
-type of fluid (temperature helps too)
-any turns/elbows in the pipe?
-Type of Pipe

Do you have a pump curve? With the above I could tell you pretty much exactly what flow rate you will get.

Basic questions:


-flow rate of fluid 75 GPM max
-room temperature water
-no bends
-1" schedule 80 pipe

Do you have a pump curve? With the above I could tell you pretty much exactly what flow rate you will get.

I'm trying to find one

That is a pretty decent run through your pipe, you will have roughly 600psi (~1350') of head loss, plus your vertical loss of 300'.

Every 33.5' = 14.7 PSI, so look on your curve at 300' head loss + 1350' friction loss (132psi + 585PSI) and look at the corresponding flow rate and you should have a rough answer. Mind you if you want a more accurate answer, rerun your calculations a few times with the new flow rate and after 2-3 iterations you will have an accurate flow rate.

This page will help you run your numbers over a few times.

You also need to know the specific gravity of the water. In hydraulic lifting (in the oilfield) the gradient used is .433 psi/ft. So you multiply by the column of water in feet by the gradient to determine psi. Not this is for freshwater 1.0 SG). If the fluid is more saltwater (1.2 SG), you will multiply the SG times the gradient times the column of water.

agrams is right, you will also have to overcome your friction loss in your pipe as well as any pressure on the end (tubing/casing pressure).

i hope your client visits this site.

But at 1500 PSI, I should be good, right?

sales people who understand what they sell

i graduated with a 2.4 in Marketing and took both math's in summer school

Dude. I'm totally going to apply for an eng job and just come to Texags to figure out all my work for me.

whatever works for you

So you fired your only engineer?

You could be fine with 1500psi discharge, but I am sure your client has a minimum acceptable flow rate he wants, which you will need to check against the curve. Depending on the pump curve you may just have a trickle of water, or if it is a PD pump you will have full 75gpm flow rate.

thanks guys, our company is going to be on the lookout for an experienced Manufacturing/Mechanical Engineer as we're in the process of moving all of our engineering from the Minneapolis area to our Houston HQ, so if y'all are looking for a new job, we may have an opening in the next 6-8 months

I think 20 GPM is about the best you could hope for with those kind of numbers for a centrifugal pump.

It's a single acting piston pump used for mineral exploration/ core drilling

This thread. Texags can literally be used for anything.

Converting to bpd for me, this seems a bit aggresive for a single piston pump.

Bernoulli

it's a triplex pump.

If you sell the pumps (and are not the manufacturer) call the pump company technical support and ask the question. They're have all the pump curves and data they need. Then you've covered yourself and can say with certainty the answer.

If you can post the pump curve for the pup you have we can help you determine if it should work.

for a piston pump you should get full flow rate. Ask them what the pressure relief valve is set at though.

Pressure relief valve is set at 1600 psi, so we're good there.

now we know who Sq16Aggie2006's sock is

Wise man. Buy your stars on your sock account to protect.

Reminds me of the PE test
