Discuss the Mohr Coulomb and Drucker prager criterion, their yield surface and examples.

Your task is to build a wastewater treatment plant to handle all of the domestic wastewater produced by a housing estate. Using population equivalent, PE = 65000, design, describe and calculate briefly the sizes of all the unit processes in the treatment plant that are going to be built. You may assume the value that is not given.

Discussion Topic: Now that you have learned about welding and bolting; how do you compare them in terms of economy (price), speed of construction, quality control, and so on; please write pros and cons for them.

4. What triggers environmental impact assessment for major projects under Australian State and Commonwealth laws? Briefly explain three weaknesses in these laws from an environmental protection perspective.

Completely and thoroughly explain how a Pareto Chart could be used to improve the operations in a company that makes any type of Lawn Furniture or Outdoor Furniture or Outdoor Gas Grills

The data obtained for a direct shear test are as follows. Normal pressure 20 kN/m2 , tangential pressure = 16 kN/m2 .Angle of internal friction = 20˚, cohesion = 8 kN/m2 . Represent the data by Mohr circle and compute the principal stress and the direction of principal planes. Also draw the failure plane.

Using Pipe-flo or Hydroflo to solve the following problem. (Report the results by including screenshoots )Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are ductile iron, cement lined, with an absolute roughness Ꜫ of 1.0 mm due to chemical deposits. Use hand calculations and show all of your work. a. Calculate the Reynolds Number (NR), the relative roughness (Ꜫ/D), and Darcy’s “f”. b. Calculate the pipe friction loss in m using Darcy’s Equation. c. Calculate the minor losses (entrance, fittings, valves, exit) in m. d. Calculate the total losses (pipe friction plus minor losses) in m.
