Selecting the size of circular connection

Selecting the size of 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.
