1. The capacity in cubic meters per hour of a clarifying centrifuge operating under these conditions is Diameter of the bowl = 600 mm Thickness of liquid layer = 75 mm Depth of bowl =400mm Speed a. 200 m³/h b. 310 m³/h = 1200 rpm/min Specific gravity of liquid = 1.2 Specific gravity of solid Viscosity of liquid Cut size of particles c. 320 m³/h d. 210 m³/h = 1.6 = 2 cp = 30 μm

For the velocity field V=A/x i^+Ay/x^2 j^where A = 2m2 s-1, and the coordinates are measured in meters. (d) Given a fluid viscosity of 0.001 Pa-s, calculate shear stress at (x, y) = (1, 3).
