Before calculating flow rates, ideal geometric shapes are chosen to represent the noncircular transverse sections. The Hagen-Poiseuille equation used with hydraulic diameter underestimates the volume ...

Oil-gas–water three-phase slug flow characterization and flow rate metering is an important issue highly related to the production safety and efficiency in petroleum industries. In this article, to ...

The coronary flow reserve (CFR), relating to the volumetric flow rate, is an effective functional parameter to assess the stenosis in the left anterior descending (LAD) coronary artery. We have ...
