Produced water is chemically very complex. The process of producing and processing produced water causes changes in temperature and pressure. The addition of treating chemicals, along with the presence of coproduced gas, oil, and likely solids, changes the produced-water properties and behavior.
Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%. It would feel much more humid on the 80 degree day with 50% relative humidity than on the 30 degree day with a 100% relative humidity.
Relative humidity can be expressed as the ratio of the vapor partial pressure of the air-to the saturation vapor partial pressure of the air at the actual dry bulb temperature. Relative humidity by partial pressure.Ï = pw / pws 100% (1).where.elative humidity can also be expressed as the ratio at actual mass of water vapor in a given air volume-to the mass of water vapor required to saturate at this volume. Relative humidity can be expressed as: Ï = mw / mws 100% (2c).
