yes, understood , this is for steady flow right?
The term in #19 follows from the equations for the stress tensor components for a viscous Newtonian fluid. Are you familiar with these equations?sir but how to get the term in #19 ? and sir one more doubt If we have a cubical element how we are gonna write the term #19 ? Is it going to remain the same??
See page 29 of http://web.mit.edu/2.25/www/pdf/viscous_flow_eqn.pdfI think I'm not familiar with that. Actually sir this isn't in my course but I'm learning it because it seems so interesting plus your great explanations . Can you provide me with only the results of cubical element or if there is any source where I can find it so that I can look after , or maybe you tell me sir.
