Been looking at the design codes for the design principle relating to the section where design should take place for flexure:
While retaining walls are not specifically adressed, the following:
Base: On the face of the column/wall
Wall: considered to be a slab => use standard cantilever span...
I am designing an "outfall sewer" for a new mine. The main source of wastewater is the change house with a total no of fixture units of 484 (29 WC-pans, 52 WHB's, 36 Urinals, 49 Shower, 10 Wash machine, 8 Wash Trough)
The way I understand the fixture unit design method is that it is based on...
We are currently installing new pumps in an old treatment plant where a completely new set up pumps (new duty and purpose) is required. The pumps are generally recycling and transfer pumps ( Qmax = 600m3/hr, so relativly small installation)The pumps are to be supplied with their own steel frame...
Regarding the performance of check valves on raw water pipelines, various options exist.
What are the advantages and disadvantages of the most common types: roller ball, swing, membrane, and spring disk? (I am not considering using control valves in my application)
I am considerng using a...
I am busy with the design of a pumped main. Regarding the design of thrust blocks: What is the accepted practice with respect to the pressure considered. I see three alternatives:
1) Normal duty point and flow
2) Pump maximum pressure (potentially zero flow, but not nessarily)
3) Surge...
