A viscous incompressible liquid of density p and of dynamic viscosity 7 is carried upwards against gravity with the aid of moving side walls. This laminar flow is stecady and fully developed in z-direction and there is no applied pressure gradient. The coordinate is fixed in the midway between the walls as shown below. –-gk liquid P,n x--d x=d I. The velocity profile in z-direction is w(x) = pg (x² – d²) + U. 2n II. To be able to carry a net amount of liquid upwards, the wall velocities need to be greater than pgd² /(27). III. If one of the walls stops, increasing the speed of the other wall to 3/2U would carry the same amount of liquid upwards. Which of the above statements are true?

A viscous incompressible liquid of density p and of dynamic viscosity n is carried upwards against gravity with the aid of moving side walls. This laminar flow is steady and fully developed in z-direction and there is no applied pressure gradient. The coordinate is fixed in the midway between the walls as shown below. 2d g=-gk liquid P, n x=-d x=d I. The velocity profile in z-direction is pg w(x) = (x2 – d) + U. 2n II. To be able to carry a net amount of liquid upwards, the wall velocities need to be greater than pgd²/(2n). III. If one of the walls stops, increasing the speed of the other wall to 3/2U would carry the same amount of liquid upwards. Which of the above statements are true?
