what values of k-epsilon?
 

I working on a continuous casting problem which similar to flow in a tank problem. I have come across a solution-file developed by fluent where they have solved a similar case. In the solution file the inlet velocity v =0.4408329m/s , k=0.00194334 and epsilon=0.00571124

I figured out that k= 0.01*v*v and epsilon=0.0667*v^3 by the above values, are these formulaes reasonable? Is there any place i can get information about the k and epsilon values?

Thanks a lot
