I have an incompressible, irrotational fluid with velocity v in the form:
v_x = c_xx x + c_xy y + c_xz z
v_y = c_yx x + c_yy y + c_yz z
v_z = c_zx x + c_zy y + c_zz z
The coefficients c_xx, c_xy, etc. are constants.
How can I determine how many independent coefficients I need to specify the velocity uniquely?
