A bar screen is inclined at 75 degree angle and with horizontal. The rectangular bars have dimensions of 10mm width * 50 mm depth and a clear spacing of 25mm. The velocity through the screen is 0.9 m/s and the total number of bars is 47 and that of clear spacing is 48. Determine the : I) velocity of wastewater in the approached channel in m/s ii) width of screen in m iii) head loss in m when the bars are clean

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.
