The chapter goes through the laws which should be recognized and obeyed before flow measurement is attempted. Certain physical laws explain what happens in the "real" world. Some of these laws explain what happens when fluid flows in a pipeline, and these in turn explain what happens to a ...
This article considers the basic terminology related to the measurement of flow in a conduit. The meaning of Reynolds number and the importance of the flow's velocity profile to the measurement process are considered. Finally, the principles of operation, advantages, and limitations of the most co...

Results of measurement of joint solubility of PuF3 and UF4 in the 46.5LiF-11.5NaF-42KF eutectic also showed, in comparison with an individual one, a significant decrease in the temperature range close to the melting point (550–600°C) [1]. At 600°C, individual solubilities of PuF3 and...
