The other is moving upward at a constant velocity v2. If we consider the fluid Newtonian, solve for the velocity profile using our newlydefined Navier-Stokes Eqns.
A tank has two rooms separated by a membrane. Room A has 1 kg air and volume 0.5 m3, room B has 0.75 m3 air with density 0.8 kg/m3. The membrane is broken and the air comes to a uniform state. Find the final density of the air.
