D23 , I would like to thank you a lot for your help , because you gave me good information. I know I bothered you alot , but in case u have any PDF files regarding the calculationS of pumping test or any good information , especifically the mathmatical examples , that can help in assumption and...

EGT01 , Thanks alot Thats what I need to know , the pumping test should be at full design rate or greater. Some Engineers answered me that I can depend on the 60m3/hr pumping test if its operated long enough to obtain a stable fluid level, and other said that you might be able to estimate...

Dear EDStainless , Can you explain to me what do you mean by 3.5X is a stretch Thanks

The test is operated long enough and they obtained stable fluid level , abouit 48 hours . So u think the data is enough to uggest the 200m3/hr capacity pump ?

All, I have a new project at which we have to install a vertical turbine line shaft pump for deep water well , the design condition for pump is : 450m head and 200m3/hr capacity . The well is drilled before two months , the contractor who driiled the well performed a pumping test at 60m3/hr...

Can we use asbestos gasket for potable water piping ?

For air piping application after the air receiver tank, 2" ss check valves will be installed. I think we are going to select UN3 type from CHECKALL VALVES manufacturer.in the manufacturer datasheets it was shown some values for the spring cracking pressure and standard cracking pressure, the...

Thanks joeswoes

If butterfly valve will be installed inside manhole, what is the best coating for this application to protect the valve from corrosion,do we need to paint this valve with epoxy as I think the humidity inside chamber is very high so can we consider it like submerged application or we can consider...

Joeswoes, What do you mean by composite ?
