(b) Figure Q3 shows a design of a plumbing system to be used in a new building. Water at 20°C is free to be pumped from reservoir A to another reservoir B at a higher elevation through two 30 m long pipes connected in parallel on a common elevation level. The difference between the water surface elevations is 10 m. The pipes are made of commercial brass and the diameters of the two pipes are 4 cm and 8 cm....
Water flows through the pipe in the figure below and exits to the atmosphere at the right end of section C. The diameter of the pipe is 2.12 cm at A, 4.24 cm at B, and 0.880 cm at C.
