The Problem with Humidity in gaz sf6 Gas-Insulated Systems

As the gas temperature increases, more water molecules pass to the gas until a new equilibrium is reached. (left) A certain gas can absorb 10 molecules of water at 86°F (30°C). If at 77°F (25°C) it can absorb 7 molecules (center), the remaining 3 molecules will form a water layer at the bottom of the container.Get price

Parts Per Million (ppm) Converter - Water Treatment and

Parts Per Million (PPM) Converter For GasesParts Per Million by Volume (or Mole) in AirReferenceThis converter calculates the measured value in units of [ppm] into units of [mg/m3] and visa versa. The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the value with the proper unit. For more theory about the use of ppm, please see the documentation below. In the input field of Molecular Weight you could either choose from the drop-down list, or you could fill in the value of the molecular weight of the gas. If the molecular weight is unknown to you, please try our Molecular Weight Calculator. By entering either the concentration in units of [ppm] or in units of [mg/m3], the value will be converted directly and displayed in the field at the bottom. The significance is automatically determined. Use extra zeroto expand the significance. [ Converters ] [ Calculators ] [ Periodic Table]Get price
