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 ...

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 ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

These are the type of flow meters that measure the velocity of liquid or gas by using the principle of ultrasound or sounds waves. Fast digital signal processors and sophisticated signal analysis ...

Introduction Have you ever poured sand out of a bucket or cereal out of a box and noticed it seems to flow' a lot like water? This is because both sand and cereal are granular materials. That means ...
