Hi thankyou for ur reply,, I read all books, all formulas r perfect, but the main problem is eta(kolmo scale)=(nu**3/epsilon)**0.25, how to calculet this epsilon,, and another is eta(Kolmo scale)=L*(Re)**(-3/4) what I have to take for L in case of Round Jet and while finding Re , what velocity i have to take, this is very very confusing question to me,, please let me know this very soon, this i need very badly,, thankyou in advance
