Go to the link below
https://www.youtube.com/watch?v=qifByJ9ezOA&t=521s&ab_channel=ZooZooSOLUTIONS
then,
1) do the tutorial
2) show color contours of the flow speed
3) Probe Fluent to calculate the flow rate at the inlet and outlet
4) perform a tracer study to calculate the mean residence time for the flow inside the tank and show a various snapshots of tracer concentration contours
5) Plot ?(?) vs ? and find t(mean)
