Analyzing low Re number flow, Navier Stokes equations take a special form
i can't understand why books always "neglect" gravity, i can think of gravity as some body force per unit mass but if it doesn't appear annymore then what force canceled it? https://ibb.co/VHMpHLs |

Gravity is often disregarded also for finite values of Re. It becomes relevant for buoyancy related problems |
