Selecting the size of the circular connection
Selecting the size of the circular connection: the maximum flow rate at the selected connection ØD is calculated with a maximum velocity in the connection of V=6 m/s. The recommended optimum velocity at the selected connection is 3-4 m/s. The recommended optimum velocity at the frontal perforation is 0.8-1.5 m/s, the maximum velocity at the frontal perforation is 2 m/s.
