Both gas and liquid flows can be measured in volumetric or mass flow rates. With noncompressible liquids, these measurements are nearly the same, sans the effects of temperature. With compressible ...

Researchers at the University of Bonn have created a gas of light particles that can be extremely compressed. Their results confirm the predictions of central theories of quantum physics. The findings ...

Heart of the experiment: the optical cavity used to create the photon gas. (Courtesy: Volker Lannert/University of Bonn) A gas of photons with nearly infinite compressibility has been created by ...

Engineering gas and steam piping systems within power generation facilities is a tough job. Balancing cost, effectiveness, and safety while anticipating changes to design requirements takes a lot of ...

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 ...
