The rate of flow of the liquid is the product of

The rate of flow of the liquid through the tube of length l and radius r, connected across a perssure haed h be V. If two tubes of the same length but of radius r and r//2 are connected in series, across the same pressure head h, find the rate of flow of liquid through the combination. If both the tubes are connected inparallel to the same pressure head, then find the rate of flow of liquid through the combination.

The rate of flow of liquid through an orifice of a tank does not depend upon

A liquid is flowing in a horizontal uniform capillary tube under a constant pressure difference P . The value of pressure for which the rate of flow of the liquid is doubled when the radius and length both are doubled is

What is venturi-meter? Derive an expression for the rate of flow of a liquid using this device.

The rate of flow of a liquid through a capillary tube is
