2. Design a circular clarifier for a flow rate of 34,560 m³/d. Use a design overflow rate of 30 m³/d-m². Assume
the clarifier has a center feed and a side water depth of 4.3 m. Use a feedwell detention time of 20 min.
Provide the following information to support your design:
• Diameter of the clarifier
• Diameter and depth of the feedwell
. Check the flow velocity across the sludge zone
• Calculate the weir loading rate

Investigation and Design of Axially Loaded Structural Members
Date:
Term:
A. Objective
1. To be able to determine internal axial load on structural members
2. To be able to design structural members with axial internal reactions
B. General Instruction
1. Write your solution legibly in separate sheets of clean bond paper.
2. Box your final answer in your solution.
C. Situation
A truss structure is an assembly of straight structural members that form triangular panels.
The assembly of triangular panels makes the truss establish a rigid configuration. In a truss
structure, connections are theoretically assumed to act as smooth pin; therefore, it does not
resist any moment or bending. Due to this magnificent behavior, truss members only resist
axial forces in the design phase that could either be compressive or tensile.
Presented in the figure is a truss that is a component of a roof framing system to be
constructed at the University Lucena City…
