Hi all,
I am currently working on a water pipeline project and am investigating a pipe burst scenario at a pump station with the aim of producing a flow rate entering the pump room in the event of a burst.
For simplification and what has been used previously on similar jobs is to model...
being in the design phase of the project, we don't really have the luxury of testing gaskets for compression at different bolt torques. We are currently undertaking an investigation into selecting the most appropriate gasket for the job and need to model effect of gasket compression and recovery...
Hi All,
I am currently researching required bolting torques for flanges on a large water pipeline, but my question relates to compression of compressed fibre gaskets.
I know that catalogues and vendors typically specify the percent compression under a specfic test stress, and also percent...
Hi,
I'm currently designing the ventillation for a number of pump stations for a large water pipeline. Essentially this will mainly involve forced air cooling, to keep the space within 5degress of ambient (i.e. no air conditioning).
My question has to with fan and and air filter...
Danger: There will be one pump station to serivce all of the demands I mentioned in my first post. I am unsure of the budget alotted to this area, but we should be aiming to minimize the number of pumps necessary.
Q Goest: I have worked on other reticulation networks under fixed speed pumps...
Hi all,
I'm stuggling with a design problem to do with pump selection for a reticulation system at a mine site.
Essentially I have to reticulate water from a storage dam to the following areas with the following minimum discharge pressures.
- Conveyor washboxes and spraybars ( constant...
Yeah most pumps will have steady loads, but some pumping applications will vary greatly, especially things like raw water which is used for washing down vehicles and stockpile sprinklers which are used to prevent ore from being picked up for the wind.
Anyway thanks guys for your help...
I can't be too specific, because what I'm doing is putting together a standard specification for pumps for an entire mine redevelopment. For those who have worked for consulting companies, you will know just how much 'fun' specs are. Anyway its mainly just a contractual document which goes to a...
Hi everyone,
I'm a graduate mechanical engineer and I was wondering if I could open up the discussion of 2-pole versus 4-pole motors. Recently I have had to specify such motors for work and wanted to find out the advantages and disadvantages of each type.
Mechanically I realize that 2-pole...
Hi,
Can anyone help me understand the purpose and function of accumulators in a pump system? Also if anyone has any information on the sizing and design of accumulators, it would be helpful.
what do you need to model it for? pretty much any fluid mechanics text will tell you in a table at the back.
lol.. if u really want to model it, put all the numbers into excel and graph it
hey pixel,
i covered this stuff in a final year mechanical and space engineering degree and there is an equation that exists to work it out, however finding that equation is quite difficult. i have it buried somewhere in my old notes somewhere and if i can be bothered finding it when i get...
Hey Telanor,
If the mass was fixed where represented by the point in your diagram, then the force will only produce angular accleration, as a constant force will produce acceleration around that point.
If the mass isn't fixed, the mass will exhibit both rotational and translational...
do a search for Newton's laws of motion. they are probably the most well known equations for scientists and engineers and worth remembering. there are a few other derivations than the one that rock freak has given you.
