Flow rateFirst Law of ThermodynamicsKinetic energyThis work presents a new equation to calculate the mass flow rate through an orifice plate for both natural gas and air samples using a thermodynamic approach. This simple equation does not contain the Reynolds number (viscosity does not appear), ...
This paper presents a practical method for computing two-phase flow rates through AGA-ASME stamdard orifice meters to a tolerance of 1.5 per cent. A rational equation is developed modifying the present single-phase metering equation by t... JW Murdock - 《Journal of Fluids Engineering》 被引量...

Once fluid flow is modelled, mass-transport equations for the pollutants are included. Generally, a diluted concentration and thus single-phase flow is assumed. Therefore, the pollutant concentration can be modelled by solving the convection–diffusion equation coupled to the stationary velocity field ...
Mass flow through the outlet orifice is modeled as a two-phase nonhomogeneous nonequilibrium process. The evacuated entropy is subtracted from the total entropy at the state of the fluid leaving the tank, then the new state with the... SA Whitmore,SN Chandler - 《Journal of Propulsion & Pow...
By a suitable transformation an equation is obtained which, to a first approximation, may be replaced by the equation for flowin an axially symmetrical jet of incompressible fluid at a sufficiently large distance from the orifice. For an ideal gas, the known solution of this equ`ation may be ...
where ρ is the fluid density, A is the cross-sectional flow area, and ue is the flow velocity at the bend. The basic equation of motion of the pipe excited by these fluid forces is: (4.15)(m+ρA)∂2Y∂t2+CI∂5Y∂t∂X4+EI∂4Y∂X4−FbX∂2Y∂X2=FbYδ(X−L)...
Where a pump or blower is being used its rev/min multiplied by swept volume is a measure of the rate of flow at the pump but cannot account for leakages. A more satisfactory device is an orifice meter in which the fall in static pressure complementary to a rise in kinetic pressure at ...
