Abstract The development of a low-cost Video Velocimeter (VIV) to estimate underwater bulk flow velocity is described. instrument utilizes simplified particle image correlation technique reconstruct an average vector from video recordings ambient particles. VIV uses single camera with set mirrors that splits the view into two stereoscopic views, allowing estimation vector. was validated in cont...

This will be a discussion of the non-invasive determination of the viscosity of a non-Newtonian fluid in laminar pipe flow over the range of shear rates present in the pipe. The procedure used requires knowledge of the flow profile in and the pressure drop along a long straight run of pipe. The profile is determined by using a pulsed ultrasonic Doppler velocimeter. This approach is ideal for ma...
