A Newtonian fluid is entered at the center of two disks with a flow rate of Q. If these disks are maintained at the same distance of H and flow is steady state, fully developed and laminar. Write the appropriate motion and continuity equations to: a) Obtain the velocity profile between the two disks. b) Determine the vertical force per unit length that is needed to hold these two disks as a function of Q, (viscosity), H and R (radius of the disk)
