Mathematical modeling demonstrates that nozzle distribution on drillbits affects the performance of the drilling fluid flow from the bit. This article is about the internal flow of nozzles on a rotary ...

When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...

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 ...
