This quantity's substantial time derivative is zero according to the continuity equation, which means that this quantity is constant for an incompressible fluid. The constant of proportionality between the kinematic and dynamic viscosities, this quantity can be measured by a pycnometer. The volume integral of this quantity is the mass. Archimedes' principle dictates that objects float in a fluid if their value for this is less than the value for this the fluid. For 10 points, name this quantity usually symbolized rho an
