An engineer monitored a flow of gasoline of about 50 m3/h and of density ,ρ 680 kg/m3 through a 10-cm-diameter smooth pipe. If the engineer used an orifice plate of a long-radius flow through the nozzle, or a venturi nozzle, all with 5-cm-diameter throat. The differential pressure gauge available was accurate in the range 30 to 60 KPa and of dynamic viscosity, μ 2.92E-4 kg/m-s. Without considering flow losses, which device is best?

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.
