IN CLASS ACTIVITY 5 Grit chamber is used to remove inorganic-inert materials from water. Here, inorganic particles such as sand settle and sludge obtained at the bottom is swiped. tats, and grasse In order to have these particles settle down, laminar flow conditions have to be satisfied. Otherwise, efficient settling cannot be reached. Settling velocity under laminar conditions can be calculated by the following equation: In this equation, g: gravitational force :specific weight of particle d:diameter of the particle :viscosity of the fluid If the hydraulic radius of the tank is 1.2m, viscosity of water at 20°C is 1.3x10 m/s, specific weight of the particle is 2.65 g/cm', and particle diameter is 0.1 mm; a) Determine the maximum velocity required to have laminar flow. b) Calculate the settling velocity of particles.
