A Novel Approach for Measurement of Peak Expiratory Velocity
It is well known that behind the orifice in a pipe, flow velocity increases and pressure decreases simultaneously. The generated sound appears that is caused by the pressure fluctuations that occur as the flow passes through the orifice. Then the flow velocity is averaged over a pipe cross-section a...
