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.
The nasal cavity lies between the base of the brain (skull base) and above the oral cavity and palate below. The nasal cavity is surrounded by paired, air-filled chambers on each side, and these lie towards the sides and above the nose (the âparanasal sinusesâ).mell is perceived through part of the roof of the nasal cavity (olfactory cleft) that is just next to the part of the brain responsible for smell (olfactory bulb and fossa). This bony partition in this area (âcribriformâ bone) is pierced by numerous nerves (âOlfactoryâ nerves) on each side.
