Explain how you check the masonry units for dimension tolerance in accordance with the relevant Australian standards.

1. For external walls, discuss the pros and cons associated with the three types of wall construction methods mentioned below using appropriate performance criteria (for example, strength, durability, thermal comfort, sound insulation and fire resistnace):        
   1. Double brick cavity wall;
   2. Brick veneer; and
   3. Concrete blocks

• Assume that the proposed house is located in Scarborough and within a 100m distance from the coast. Note that the site classification is Class A’

Which of the joint types you recommend for this project and defend your choice. Refer to the project specification to know the masonry construction types recommended for this project

Case Studies of Illegal and Unethical Behavior:

A professional engineer failed to apply his signature and seal to an acoustical

engineering report prepared under his supervision by an unlicensed person.

.

You should identify the codes and laws that prohibit such activities in your state.

Ladder diagram image of the full solution before simulation is started.
 Testing scenarios with images. Here you will show pictures of the LOGO program
during simulation of a particular scenario. Write an explanation for each step of
the scenario showing why such input sequence causes the output sequence
shown. Include images of the LOGO simulation which demonstrate that indeed
you have observed these test scenarios.

A 280m long equal tangent sag vertical curve has its PVC at chainage 2950.00m and elevation 76. 520m.The initial grade is -3.89% and the final grade is 1.02%. (20)
a. Make a neat free hand drawing to illustrate a long section of this curve.
b. Calculate the chainage and elevation of PVI
c. Calculate the chainage and elevation of PVT
d. Calculate the chainage and elevation of the lowest point on the curve.

by using epanet software, how to collect the data for elevation, pipe length, pipe diameter, base demand and pipe roughness

The 1.3-m-diameter tank is initially filled with gasoline. There is a 3.2-cm-diameter orifice in the bottom. If the orifice is suddenly opened, estimate the time (minutes) for the fluid level to drop from 2m to 1.2 m. Use SG (gas) = 0.66, Cd = 0.63

A horizontal pipeline conveying oil (s = 0.8) contains a 60◦bend in which the internal diameter reduces from 200 mm to 100 mm. If the pipe joints on either side of the bend exert no restraint on it, what will be the force an anchorage must resist when the pressure head and the mean velocity of the fluid at entry to the bend are 12 m and 3 m/s respectively? Find also the direction in which the force acts.

rapid sand filter will be constructed for average flow rate of 0.06 m3 / h.

Design (...find dimensions...) and draw the filter.

Your consultancy is planning the layout for a city centre train station. This is a terminal station in which all trains have to enter forwards and leave by reversing out. (Examples of this type of station are King’s Cross or Euston stations in London, or Gard du Nord in Paris, home of Eurostar.)

Explain how you would establish the space, flow and activity relationship requirements for the train station layout. Within your answer identify the types of information you would need and how it would be analysed.

1. Three pipelines as described below are arranged in 3 modes: 1) series 2) parallel and 3) series-parallel with pipeline A as the main that feeds pipelines B and C which are in parallel. In all three modes the total pressure drop from the system inlet to outlet is 350 feet. The friction factor (f) for all pipelines is 0.014. Calculate the flow and pressure for each pipeline in all 3 modes and list the answers in the table. Attach your calculation sheets.
