hello sir, I am solving turbulent flow in a rectangular manifold. my question is in inlet boundary condition i want give velocity as input condition. since my diameter is 1.7 cm I assigned a value of 0.5 m/sec in my z direction. Now i find a tab for average velocity when i opt my turbulence type for intensity and length scale. my question is how much should my value be in average velocity ??? Should my z-direction velocity be equal to the average velocity or something else. Can anyone explain me the concept behind this
