The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

The steady state solutions of two mathematical models are used to evaluate Münch's pressure-flow hypothesis of phloem translocation. The models assume a continuous active loading and unloading of ...

Industrial and chemical processes ranging from brewing to polymerization depend on delivery of accurate quantities of gases or liquids. It is possible to measure rates of delivery in terms of either ...

As today's science and engineering focuses more and more on micro technology, the requirement to be able to measure and control extremely low gas mass flow rates has become very important. With ...
