Thanks all for your advise

This is a dredging works where the dredged material will be stockpiled. We are going to conduct 12 items of testing (base on Dutch Standard) for any contamination/heavy metal existance in the stockpile. THe stockpile height is 5m and one big area may cover up to 100,000 m3. Is there any...

Thanks StephenA for this useful references

basically we need to remove some boulders under the old building to construct new underground hall, it required us to do the quiet and safe breaking work due to the location of the area at the middle of the Kuala Lumpur City. Where can i refer the Bristar you said, just before this, one of my...

Hello What basiccaly the process and chemical used in breaking boulders? and what spec are these? where can i get the references

Which standards give details on the frecuency of chemical test in soil

Where can i find standards for chemical test in soil

tq

Hi Gorkus May i give some ideas? For me, it maybe possible for if you can use the normal pump. Then, just insulate it with anti corrosion coatings and this will avoid the pump surface to be corroded. The impeller of your pump will easily built with SS. TQ

the water temperature measured here is about 16 deg Celcius

Yes i know that the atmospheric is not only the cause, just want to confirm the effect. Any comments on water temperature? is it also one of the source of the cavitation at this level? TQ for all the comments

because now my pump operating at 5600ft from sea level and we found a cavitation occured. just want to relate it with atm pressure tq

how big is the effect?

Any comments for relation between fluid temperature and atmospheric pressure to Cavitaion. if the pump used at sea level, there must be a different with the pump used at high altitude (on top of the hill). The water boiling temperature also will be change. Is it can be the effect in pump...
