How OBR calculated for DM plant having SBC and SBA?
DM plant OBR is calculated by knowing the following things. 1.Total ionic load this can be found in raw water quality. 2.Total exchange capacity of resins 3.Quantity of resin in ion exchange vessel vessel 4.Flow of water
Hypobromite is used to purify contaminated water. what is the formula for hypobromite?
The formula for hypobromite is OBr-.
How do you convert mol dm-3 to molL-1?
It is supposed to be mol/dm-3 Actually, 1 dm cube is the same as 1 litre. Therefore, there is no need of conversion. Both are the same.
What is Difference between promethazine and promethaziine dm?
Promethazine is an antihistamine medication used to treat allergy symptoms, while Promethazine DM is a combination medication that also contains dextromethorphan, a cough suppressant. Promethazine DM is used to treat cough and cold symptoms in addition to allergies.
What volume of the 0.200mole dm-3hcl is required to neutralize 25.0cm3 of 0.200 moldm-3 BaOH2?
To neutralize the Ba(OH)2, we need an equal number of moles of HCl. The molarity of Ba(OH)2 is 0.200 mol/dm^3, so the number of moles present in 25.0 cm^3 is (0.200 mol/dm^3) x (25.0 cm^3 / 1000 cm^3) = 0.005 mol. Since HCl and Ba(OH)2 neutralize each other in a 1:1 ratio, we need the same number of moles of HCl. Therefore, the volume of 0.200 mol/dm^3 HCl needed is (0.005 mol) / (0.200 mol/dm^3) = 0.025 dm^3, which is equivalent to 25.0 cm^3.
What is OBR in DM plant?
OBR in a DM (Demineralization) plant refers to "Online Blowdown Regulation." It is a process used to control the concentration of dissolved solids in the demineralized water by periodically removing a portion of the water (blowdown) to maintain water quality. This helps prevent scaling and fouling in the system, ensuring efficient operation of the plant. Proper OBR management is crucial for optimizing the performance and longevity of the demineralization process.

When was OBR Open Building Research created?
OBR Open Building Research was created in 2000.
How DM plant are design?
Since there is continuous withdrawal of steam and continuous return of condensate to the boiler, losses due to blowdown and leakages have to be made up to maintain a desired water level in the boiler steam drum. For this, continuous make-up water is added to the boiler water system. Impurities in the raw water input to the plant generally consist of calcium and magnesium salts which impart hardness to the water. Hardness in the make-up water to the boiler will form deposits on the tube water surfaces which will lead to overheating and failure of the tubes. Thus, the salts have to be removed from the water, and that is done by a water demineralising treatment plant (DM). A DM plant generally consists of cation, anion, and mixed bed exchangers. Any ions in the final water from this process consist essentially of hydrogen ions and hydroxide ions, which recombine to form pure water. Very pure DM water becomes highly corrosive once it absorbs oxygen from the atmosphere because of its very high affinity for oxygen. The capacity of the DM plant is dictated by the type and quantity of salts in the raw water input. However, some storage is essential as the DM plant may be down for maintenance. For this purpose, a storage tank is installed from which DM water is continuously withdrawn for boiler make-up. The storage tank for DM water is made from materials not affected by corrosive water, such as PVC. The piping and valves are generally of stainless steel. Sometimes, a steam blanketing arrangement or stainless steel doughnut float is provided on top of the water in the tank to avoid contact with air. DM water make-up is generally added at the steam space of the surface condenser (i.e., the vacuum side). This arrangement not only sprays the water but also DM water gets deaerated, with the dissolved gases being removed by an air ejector attached to the condenser.

Convert dm to 7m?
7m.........dm
1M 60dm plus 30 dm equals?
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.
Which one bigger 50 dm or 30 m?
dm = decameter 1 dm = 10 m answer: 50 dm
