Aviscous liquid is sheared between two parallel disks of radius �, one of which rotates with angular speed ω, while the other is fixed. the velocity field is purely tangential, and the velocity varies linearly with z from: �; = 0 at � = 0 (the fixed disk) to the velocity of the rotating disk at its surface (� = ℎ). derive an expression for the velocity field between the disks.

Upper disk rotates at a constant angular velocity. The velocity at any height from stationery disk, say at x metres

where v is tangential velocity at radius r from the centre of disk

The radial component of velocity is given as

The z component of velocity is also given as  

W=0

Total velocity,

are there options? cause you ain’t. real specific

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
