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.
Nasal cavity. The nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face. Each cavity is the continuation of one of the two nostrils.n the sides of the nasal cavity are three horizontal outgrowths called nasal conchae (singular concha) or turbinates. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum.
