The CNS is educated at an advanced level to care for patients in one of the six described populations and across the continuum of care. The role of the CNS encompasses the patient, the nurse and nursing practice, as well as the healthcare organization and system.
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).
Absolute humidity is the mass of water vapor divided by the mass of dry air in a volume of air at a given temperature. The hotter the air is, the more water it can contain. Â­Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creatinÂ­g the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain -- it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.
