Derive, using the Navier-Stokes equations, the differential equation for the velocity v-theta (r). after use that expression to calculate the answer in cm

Complete (1) the velocity distribution derivation v(r) for the Stormer Viscometer and (2) Calculate for the viscosity, , of a solvent. - Problem (1): Answer the v(r) (in cm/s ) at r=4.95cm (i.e. the linear velocity). ---Using the completed v(r) equation you finished earlier
