All 305-mm (12-in) lines are increased to 355 mm (14 in), the 355-mm (14-in) lines are increased to 405 mm (16 in), and the 405-mm (16-in) line is increased to 450 mm (18 in). Determine the flow in each line, the velocity in each line, and the pressure at point G assuming points A and G are at the same elevation and the pressure at A is 500 kPa (75 lb/in²).

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
