It can improve air permeability, bond shear strength, water stability and aging resistance. For stationary, creeping, incompressible flow, i.e. D(ρui)/Dt ≈ 0, the Navier–Stokes equation simplifies to the Stokes equation, which by neglecting the bulk term is: where μ is the viscosity, ui is the velocity in the i direction, gi is the gravity component in the i direction and p is the pressure. Assuming the viscous resisting force is linear with the velocity we may write: honeywell l6006c1018 aquastat controller
