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.

This problem is useful for the preliminary design of a hydroturbine. From the material learned in this chapter, it is fairly simple to estimate how much power a hydroturbine can generate, given only the flow rate of water and the elevation difference upstream and downstream of the dam. A dam has a gross head of 15.5 m and a flow rate of 0.22 m3 /s. Approximating the overall efficiency of the turbine/generator to be 75%, estimate the electrical power (in kW) that couldbe produced.
P7.) A pipe system, connecting two reservoirs whose difference in water surface elevation is 13 m, consists of 320 m of 600 mm diameter pipe (pipe 1), branching into 640 m of 300 mm diameter pipe (pipe 2) and 640 m of 450 mm diameter pipe (pipe 3) in parallel, which join again to a single 600 mm diameter line 1300 m long (pipe 3). Assuming f = 0.032 for all pipes, determine the flow rate in each pipe. Subject: fluid mechanic Lesson: *Conservation of Energy *Fluid Flow in Pipes
