The Superficial Velocity Formula Superficial gas velocity (aka superficial flow velocity) is an estimate of how quickly a fluid passes through an object (e.g. a pipe) or a porous medium (e.g. gravel). It's calculated using the following formula: us=QA •u_s_ is the s...

How to add gas velocity in turbulent bubbly phase?Login
By using the thirteen moment equations for a binary gas mixture of Maxwell molecules, the expressions for the velocity-slip and temperature difference between species in the source-flow expansion into a vacuum are obtained for the case of a small Knudsen number. Then, the velocity-slip and tempe...
Applied velocity versus offset (VVO) to validated & characterized fracturing zone in intra Baturaja Formation, South Sumatera Basin The velocity versus offset (VVO) as new geophysical method can be applied to detect some geological phenomenon, such as hydrocarbon trap, structural-fracture anomaly, fac...
The relation between circulation rate and critical gas velocity for complete suspension was discussed taking into account the mechanism for suspending solid particle in horizontal pipe.关键词: Circulation rate Complete suspension Critical gas velocity Short size draft tube Slurry bubble column Solid ...
The centrifugal force on the liquid droplet (Fc) was determined by the formula below:(1)Fc=πdL36ρL(vθVT2DVT/2) From equation (1), it was established that the size of the inertial centrifugal force was associated with the gas flow velocity, the diameter of the vortex tool, the densi...
We classify the solutions of the \\CVS{} equation and find the analytical formula for the velocity field for arbitrary background strai... A Migdal 被引量: 0发表: 2021年 Time scale, objectivity and irreversibility in quantum mechanics It is argued that setting isolated systems as primary ...
may be used in very large cross-sectional ducts or to measurewind speedin the open air. They may depend on the rotation to generate a small electrical current, which can be calibrated as a speed, or the number of revolutions may be inserted into an empirical formula. A typical example is...
A pipe with a large diameter of about 1.5 cm and a length of 1.3 m connected the two tanks. At the outlet of the channel, two GEFI® rotary vacuum pumps (Pfeiffer Vacuum, Aßlar, Germany) of the same model were used in parallel to achieve the highest mass flow rate through the ...
