Choke Manifolds Flowback, Well Testing SLB - Schlumberger
Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a … Meer weergeven If the fluid is a liquid, a different type of limiting condition (also known as choked flow) occurs when the venturi effect acting on the liquid flow through the restriction causes a decrease of the liquid pressure beyond the … Meer weergeven If the upstream conditions are such that the gas cannot be treated as ideal, there is no closed form equation for evaluating the choked mass flow. Instead, the gas expansion … Meer weergeven The flow through a venturi nozzle achieves a much lower nozzle pressure than downstream pressure. Therefore, the pressure ratio is the comparison between the … Meer weergeven All gases flow from higher pressure to lower pressure. Choked flow can occur at the change of the cross section in a de Laval nozzle or through an orifice plate. The choked velocity is observed upstream of an orifice or nozzle. The upstream volumetric … Meer weergeven The minimum pressure ratios required for choked conditions to occur (when some typical industrial gases are flowing) are presented in … Meer weergeven The flow of real gases through thin-plate orifices never becomes fully choked. The mass flow rate through the orifice continues to … Meer weergeven Figure 1a shows the flow through the nozzle when it is completely subsonic (i.e. the nozzle is not choked). The flow in the chamber accelerates as it converges toward the throat, where it reaches its maximum (subsonic) speed at the throat. The flow … Meer weergeven Web13 apr. 2024 · Product specifications. 10,000- to 15,000-psi working pressure. Sweet or sour service rated.
