Where the two streams combine, equalizing their velocities through momentum transfer. Use INDEX(MATCH(

For example, you can embed a semi-empirical equation for entrainment ratio based on curve fitting of design data from reputable manufacturers like Schutte-Koerting, Croll-Reynolds, and Graham. Such an equation is generally satisfactory for entrainment ratios between 0.2 and 1.0. Excel Cell Description B4 Pressure of the driving
