[answerhappygod]

Derive and formulate the differential momentum equations forthree-dimensional fluid flow by using a 3D rectangular element. Youmust draw the element and label all forces acting on all faces andvolume appropriately. The origin of (x, y, z) must be placed at thecenter of the element. You must show a complete derivation for allcomponents and state all assumptions made.
