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.
Know your nose The nasal cavity is divided into two passages by the nasal septum. The nasal septum is composed of both bone and cartilage and extends from the nostrils to the back of the throat. Bones called nasal conchae project into the lateral walls of the nasal cavity, forming a series of folds called turbinates.here are three turbinates on each side of the nasal cavity and are lined by a thick mucous membrane. Turbinates greatly increase the surface area of the nasal cavity. During inhalation air is directed over and under the turbinates. Lining the nasal cavity is a mucous membrane rich with blood vessels.
