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).
Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity, which will depend upon the current air temperature. Relative humidity is the term weather forecasters use most often. A relative humidity of 100% means that the air can't hold any more water vapor. It's totally saturated. When this occurs, it can rain. In fact, the relative humidity must be 100% where clouds are forming for it to rain. However, at ground level where the rain lands, the relative humidity can be less than 100%.
