1- The disk of a computer hard drive is approximated as shown in the schematic, with the disk spinning at an angular speed of n in Its cylindrical enclosure. Assuming laminar, incompressible flow in the enclosure driven by the disk motion, starting from the full governing equations of fluid dynamics (presented on the next page) and making the relevant simplifications with suitable justifications, b. neglecting any radial fluid motion, derive the simplest possible differential expression that relates static pressure to Ve=f(r,z);
