(5) Derive the continuity equation in spherical coordinates in two ways. (i) Starting from first principles using an infinitesimal control volume fixed in space. To do this, set up a small elemental control volume in the spherical coordinate system, and identify the rates of inflow/outflow of mass through each face of the control volume; setting the net inflow equal to the rate of mass accumulation in the element. (ii) Starting from the vector form of the continuity equation derived in the course note and using the divergence and/or gradient operators for spherical coordinates.
