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).
The new definition says absolute humidity is the mass of the water vapor in a volume divided by the mass of dry air in the said volume. This definition is much convenient when dealing with pressure changes. However, to avoid confusion, the first definition is renamed as the volumetric humidity. Relative Humidity. Relative humidity is important when the real effect of the humidity is concerned. To understand the concept of relative humidity, there are two concepts that are needed to be addressed first. First one is the partial pressure.
