where the velocity is the actual average fluid velocity in the vena contracta and jet diameter is the diameter of the vena contracta. This equation can be obtained by evaluating the energy dissipation rate at 8d, the limit of applicability of the equation found in THE INFLUENCE OF VISCOSITY ON MIXING IN JET REACTORS by Jo BALDYGA, J. R. BOURNE* and R. V. GHOLAP.
