1. Design a PVC sanitary sewer collection system for the Village of Waffle (Figure P-17-24 B, shown below) by
preparing a sewer design table similar to that shown in Example 19-2 and a profile drawing similar
to Figure 19-13b B. You only need to show the calculations for the pipes running along Bacon Road and
Eggs Road, starting at point F and ending at Point B in the figure below. Your design should comply with the
requirements specified in Chapter 30 of the 10 States Standards for Wastewater. Use the following
assumptions:
0
о
о
Average daily flow rate is the same as average daily water demand, 9.2 m³/hr
Peaking factor for peak dry weather flow is 6.2
Peak wet weather flow is equal to the peak dry weather flow plus an assumption for infiltration and inflow
at 40 L/d-mm-km of pipe

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

- Name: Course: Mechanics of Deformable Bodies 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…arrow_forward1- A two-lane highway (two 3.6 m lanes) has a posted speed limit of 100 km/h and, on one section, has both horizontal and vertical curves, as shown in the figure below. A recent daytime crash (driver traveling westbound and striking a stationary roadway object) resulted in a fatality and a lawsuit alleging that the 100 km/h posted speed limit is an unsafe speed for the curves in question and was a major cause of the crash.
