1.6 Evaluate the radial component of the inertia term (u V)u in cylin- drical coordinates using the following identities: x = R cos 0 y = R sin e ue, + vey= ur er + uo eo and any other vector identities from Appendix A as required. Here, R and 0 are cylindrical coordinates, up and u, are the correspond- ing velocity components, and er and e, are the unit base vectors. 17 Fulate the
