Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

In a horizontal pipe water flows at a rate of 9.1 L/s. Here, the pipe has two sections, one with a diameter of 10.16 cm and the other with a diameter of 5.08 cm, with a gradual smooth reducing section. In this case, a mercury manometer is used to measure the pressure difference. If friction is negligible how would I find the differential height of mercury between the two sections? If the manometer on the 5.08cm pipe section was replaced with a pitot tube how would the reading change? any help would be deeply appreciated
