Hi everyone,

I am using a online y plus calculator to work out the y plus value for a fuel bundle.

http://www.pointwise.com/yplus/

In regards to the reference length, I have been told by peers to utilise the hydraulic diameter using 4A/P

where A is the cross sectional area, and P is the wetted perimeter.

Is this correct or is there any other better ways to undergo this.

Thank you in advance
