laminar or turbulent
 
Hi, I'm wondering wether the flow is laminar or turbulent.

I got a box 300*250*135mm filled with water 35C
I got an flow of 0,139 kg/s water coming in through 25 x 3mm nozzles, and an pressure outlet defined face.

I know that the flow right at the nozzle has a Re of 2300 and a speed of 0,8 m/s, which might be considered turbulent, but the viskosity speed in the box is much lower.

so my question: do i have to calculate the flow laminar or turbulent?
if i compare both simmulations i get different results...

thanks for your help
Sebastian
