Controlling flow of a fluid-power system does not necessarily mean regulating volume per unit of time from a valve. Flow rate can be specified three different ways, so it is important to be aware of how flow is to be specified or measured: Volumetric flow rate, Qv, expressed in units of in.
The nasal cavity is the are inside the nose, separated from the oral cavity (the area inside the mouth) by the nasal spine. The purpose of the nasal cavity is to deliver cleaned, moistened, and warmed air to the pharynx (throat). The cavity is lined with mucous that has tiny hairs on it.
