WebA Venturi flow meter is a type of differential pressure flow meter that generates a flow measurement by measuring the pressure difference at two different locations in a pipe. This pressure difference is created by constricting the diameter of the pipe, which causes an increase in flow velocity and a corresponding pressure drop. WebResults of the differential transducers are used to understand the backward erosion process and to measure the head loss in the riser due to the suspension of eroded soil in the riser. Three dimensional finite element software is used to mimic the erosion occurs for each test and calibrated using the results of the experimental data. grass albedoWebApr 10, 2024 · A performance enhanced CaptiveSpray differential ion mobility device was designed and constructed by incorporating a circular channel and a gas flow homogenizing channel (GFHC) between the CaptiveSpray ion source and planar differential ion mobility spectrometry (DMS).
