We'll now set the value of the velocity setup the boundary conditions at the wall, centerline, inlet and pressure at the outlet.

Problem Setup > Boundary conditions

We don't need to set any parameters for the wall zone. FLUENT will automatically detect that this location should be set as a wall based on its name. Verify this by selecting that zone and looking at its type in the drop down menu.

Next, let's look at the centerline. Since we are solving an axisymmetric problem, we will set the centerline as the axis. Set centerline to axis boundary type, using the drop down menu.

Choose inlet and click on Edit.... Change the Velocity Specification Method to Magnitude, Normal to Boundary. Enter 1 m/sfor Velocity Magnitude. This indicates that the fluid is coming in normal to the inlet at the rate of 1 meter per second. Select Intensity and Hydraulic Diameter next to the Turbulence Specification Method. Then enter 1% for Turbulence Intensity and 0.2m for Hydraulic Diameter. Click OK to set the boundary conditions for the inlet.
