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.
It is: 3.4+5.65+6.85 = 15.9 dm
1 m = 10 dm ⇒ 1374 m = 1374 x 10 dm = 13740 dm
dm and dm refer to the same unit, decimetres. Therefore, 25 dm is equal to 25 dm (decimetres). Another, similar unit, the decametre, is abbreviated dam.
First, convert m to dm. 1 m = 10 dm 6 m = 60 dm Thus, 36 dm/ 60 dm = 3/5
The Outflow Bypass Recycle (OBR) of a DM (Demineralization) plant is a system used to divert a portion of the treated water from the outlet back into the inlet for further treatment. This process helps in improving the overall efficiency of the demineralization plant by enhancing the purity of the outlet water.
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
OBR Open Building Research was created in 2000.
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 For this purpose, a storage tank is installed from which DM water is continuously withdrawn for boiler make-up.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.

an obre is a building...........not quite very famous though

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.
dm = decameter 1 dm = 10 m answer: 50 dm
