Answer #1

Continuity equation for incompressible flow (constant density flow) conservation of mass Navier Stokes equation conservation of momentum Acceleration (change of velocity with time) Incompressible flow: - Flow is incompressible if volume and thereby density of fluid changes insignificantly in fluid flow. For all practical purposes, liquid can be considered as incompressible. This means that pressure and temperature changes have little effect on their volume. For all practical purposes, liquid can be considered as incompressible.
