If a point is at a depth 'h' from the free surface of a liquid open to the atmosphere (where the pressure is the atmospheric pressure Patm), then the gauge pressure Pgauge at that point is given by:

The ratio of the specific weight of a liquid to the specific weight of a standard fluid is known as:

The magnitude of the buoyant force depends on the _____________.

In incompressible fluid dynamics, the continuity equation is ∂u/∂x + ∂v/∂y + ∂w/∂z = 0. What physical law does this equation represent?
