The setting velocity of a particle is 0.002 m/s and the overflow rate of a settling tank is 0.008 m/s.
(a) what percent of the particles does the settling tank capture?
(b) If the particles are flocculated so that thie rsettling rate is 0.05 m/s, what fraction of the particles is captured?
(c) If the particles are not charged, and another settling tank is constructed to run in parallel with the original settling tank, will all of the particles be captured?
What are two or three quality management tools used in data collection? What types of quality management tools do you utilize to make personal or business decisions? How do you use these tools in the decision-making process?
A flow has circular streamlines. At t=0 the flow is in the clockwise direction and the angular velocity is pi rad/s. This flow exists for 1 s, and then reverses to counterclockwise with an angular velocity of -pi rad/s for 1 s.
A three-span continuous beam ABCD with three equal spans supports a uniform load with intensity q. Determine all reactions of this beam and draw the shear force and bending moment diagrams labelling all critical ordinates.
If the column is subjected to an axial compressive force of 800 kN, determine the required diameter of each reinforcing steel bar so that one-third of the load is carried by the steel and two-thirds by the concrete. Assume Esteel= 200 GPa and Econ..
A particle with a mass of 0.5 kg has a velocity of 10 m/s in the x-direction at time t = 0. Forces F1 and F2 act on the particle, and their magnitudes change with time according to the graphical force-time history shown.
