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.

Question

Consider water flowing through the pipe network shown in the figure below. The flow can be
assumed stationary inside Reservoir 1 and Reservoir 2. The inlet of Reservoir 2 is located 2 m below
the outlet of Reservoir 1. The pressure in Reservoir 1 is 50 kPa, and the pressure in Reservoir 2 is 30
kPa. Section 1 of the pipe network has a length of 5 m and a diameter of 0.2 m. Section 2 of the pipe
network has a length of 2 m and a diameter of 0.15 m. Section 3 of the pipe network has a diameter
of 0.18 m and an unknown length. The mass flow rate through the pipe network is 160 kg/s. Minor
total pressure losses in the elbows connecting the sections may be neglected. Calculate the length
of Section 3 of the pipe network. Assume that the friction factor through all sections is 0.01.
