The Hagen-Poiseuille equation is, perhaps, the most famous solution set of this.
The Hagen-Poiseuille equation is, perhaps, the most famous solution set of this. This equation is reduced to Euler's equation by the assumption that the divergence of the viscous stress tensor is zero and though this lemma is nigh on impossible to solve analytically, it must be made significantly more complicated for flows with non-constant density or viscosity. For ten points, name the non-homogenous partial differential equation that represents conservation of momentum in an isochoric Newtonian fluid flow.
