Test Preparation on Chemistry Test Preparations On Fluid Mechanics Part 2

The ratio of average fluid velocity to the maximum velocity in the case of laminar flow of a Newtonian fluid in a circular pipe is

The line of action of the buoyant force passes through the center of gravity of the

Mass velocity is independent of temperature & pressure, when the flow is

Very small pressure difference (< 5 mm water coloumn) can be most conveniently measured by a/an __________ manometer.
