# Turndown Curve 2

The following table show the specifications of the turndown 2.

 Pipeline (m) 25 Riser (m) 13,5 Radius bend (cm) 50 Liquid mass fraction (-) 0,9957 Gas mass fraction (-) 0,0043

Four different total mass flow rate were simulated in this case. These simulations represent the four points to the left from the lowest point. It will be pay specific attention to the relation between the turndown point (lowest point of the turndown curve) and the existence of severe slugging.

For the following set of figures, the graph to the left indicates the point that is going to be simulated in a transient fashion. The graph to the right, shows in this order: the pressure at the pipeline bending, the volume fraction at the pipeline bending, the volume fraction at the pipeline outlet, the mass flow rate of the liquid at the pipeline outlet and the mass flow rate of the gas at the pipeline outlet.

• Point 1, Total mass flow rate $Ft\;=\;0,2878\;kg/s$

• Point 2, Total mass flow rate $Ft\;=\;0,5756\;kg/s$

• Point 3, Total mass flow rate $Ft\;=\;0,8634\;kg/s$

• Point 4, Total mass flow rate $Ft\;=\;1,1512\;kg/s$
