In the diagram above, the gas in the pipe has specific gravity S (molecular weight Mw) and is at temperature T1 and pressure P1. The gas leaks out a hole of diameter d (or crack of area A) at flow rate W, velocity V2, Mach number M2, pressure P2, and temperature T2. Gas disch...

Thermal Molecular Velocity of Gas Molecules Formulas and Calculator Gas molecules in a vessel move back and forth in different directions and at different speeds. Their velocity distribution corresponds to a bell curve having its peak at the most probable velocity Probable Velocity cw= [ ( 2 · R...
This application calculates the flow rate through a large-diameter orifice using the approach outlined in ISO 5167 2:2003. Orifice meters use the pressure loss across a constriction (that is, the orifice plate) in a pipe to determine the flow rate. The formulas are valid for the following ...
Comparison of the computed results with the experiments of the sieve tray shows that the proposed model can successfully simulate the velocity field on the tray.关键词: sieve tray gas - liquid two - phase flow pseudo - three - dimension simulation two - fluid turbulence model 被引量: 33 ...
The wet tubular fabric is initially spread to flat form and then guided in a controlled manner over a so-called Mach nozzle, at which high velocity gaseous medium, usually steam, at speeds approaching the speed of sound and above, is discharged directly through the fabric, which is maintained...

its pulse-echo response would be similar to a stationary or slow-moving target in the fast-time dimension and thus produce clutter in the PW spectra. However, the bandwidth of this clutter would be a function of its flow velocity in the axial direction (Yu et al., 2006) and can be cal...
where C is the gas concentration in the core sample, kg/m3; t is the time, s; r is the radial distance, m; ρg is the gas density, kg/m3; and 𝑢 u¯ is the velocity of the gas flow along the radial direction, m/s. Taking the adsorption and slippage effects into account,...
