Research output: Contribution to journalConference articlepeer-review


A tube flow viscometer complete with data acquisition system was designed and developed for continuous measurement of pressure drop and flow velocity. Experiments were carried out with five fluids in laminar flow region using stainless steel tubes of different diameters. The flow parameters determined with the tube viscometer after slip correction and a Brookfield viscometer were correlated for estimating the pressure drop indirectly. Finally, it was shown that neural networks could accurately predict the pressure drop in tube flow without making any correction for wall-slip from the input data on tube diameter, fluid density, mass flow rate, and flow parameters determined with a Brookfield viscometer.
