friction factor
 
hi i have one rectangularduct probleme, how i can get the friction coefficient from starcd in order to campare that with the experiment thanks

How is YOUR "friction factor" defined ?

Hay Joern

the friction coefficient for the rectangular duct is f=(8*wall shera stress)/(density*Ub*Ub)Ub is the bulk velocity thanks

Check the commands operate, *get, *set and summ which should be enough to calculate your factor. Don't forget to enable the saving of the wall force data.

Hi Sabatini:

you need "getw" also.
