| Sep 18, 2019 at 6:58 | comment | added | Patricia GC | It is a force field and the control volume is supposed to be the same as the fluid volume. But I don't understand the correspondence between the surfaces and hence the surface forces | |
| Sep 18, 2019 at 5:45 | comment | added | Emil | What is F? Is it a force field? In that case, in your equation, isn't the control volume different from the fluid volume? How can the fields be equal if the volumes differ ..? | |
