this is my question to any one to answer mahendra
ph of DM water is 6.5 to 7.1 conductivity of Dm water is near 000
By definition, the pH of demineralized water is 7.0. Note that "pH" is always written exactly like this "pH", so why not join the rest of the world and do so? Note, for abbreviations like DM, the "demineralized" should always be written out in full on its first appearnce. Otherewise, most people will not know what on Earth you mean. D.A.W.
shelf life of DM Water
The aluminum alloy AA 6061 is not soluble in water at room temperature.
Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.
Unit of dm water conductivity is microsiemens/cm
ph of DM water is 6.5 to 7.1 conductivity of Dm water is near 000
High quality of DM water is important for such industries as power generation, semiconductor and pharmaceutical where there are strict regulatory requirements. The most common way to measure very low levels of ionic impurities in ultra pure water is on line analysis of conductivity and resistivity. DM water is often exposed to CO2 from the air, which increases its conductivity and gives the appearance of a contaminant in the water. Depending on CO2 concentration in incoming air water conductivity can be increased to ~0.8-1.5 µS/cm. CO2 breather or CO2 Scrubber for DM Tanks allows you to keep stable pH and low conductivity of DM water.
PH : 6.5 to 7.5 Conductivity : Less than 10 µs/cm. Chloride : Less than 0.5 ppm. L. GRAGORI, Tiruchirapalli-620 014,India.
what will be the TOC content in DM water
DM meaning demineralized water. Pure water is actually a poor conductor. Impurities in the water create ions which allow conduction to take place.One use of non-conducting water would be in a closed loop cooling system for transmission tubes (like for RADAR), where the tubes are energized to several thousand volts, and you do not want current to flow through the water and short out the system.

7m.........dm
Since 1 m = 10 dm, then 1 m 60 dm + 30 dm = 70 dm + 30 dm = 100 dm = 10m or 1 m 60 dm + 30 dm = 1m 90dm = 10 m.
