EXAMPLE QUESTION WITH ANSWER** I need the one above answered.

2. Design of a Grit Chamber (12 marks) Design a grit chamber for the town of Shepparton, with a polulation of 50,000 with a water consumption of 135 litres per capita per day. You have been asked to design a horizontal flow grit chamber with rectangular cross section requires to remove the grit particles before flowing into primary sedimentation tank. Assume grit particle with radius of 0.12 mm and a specific gravity of 2.65. Assume Stoke's law applies. Problem 4 Design a horizontal flow grit chamber to remove grit of size greater than 0.2 mm if the through flow is 10,000 m3/d. The specific gravity of the particle is 1.9. Assume Stoke's law applies.
