Hi im trying to understand the formula for pipe deflection in the AWWA M11 page 75. Using the metric formula (7-6M), i calculated the deflection to be 2.27mm for a 6m long 250mm OD steel water pipe with 4.55mm wall thickness.
Is this deflection calculation correct? I also cant seem to get the...
Im relatively new to the water world. For a pressurised steel water supply pipeline laid in relatively soft ground, what is the normal approach to minimize differential settlement between the pipes and chambers and anchor/thrust blocks?
Is the option of piling the chambers to a floating length...
Hi all,
I have a question on the effect of welding heat on the internal cement lining of mild steel water pipes. Is it possible for the heat during welding of collars, flanges etc. to damage these cement linings?
Currently involved in a project where we have a 15 inch ND MSCL pipe for a...
I have a question on mscl water pipe design. For a 30' equal mild steel tee, according to awwa m11 on reinforcing plate design we have to use wrapper plates as the ratio of branch/main diamter is 1.0 (more than 0.7). However looking at the shop drawings given by a few pipe manufacturers they...
Hi, my question is more towards Autodesk Civil 3D and Storm and Sanitary Analysis which is also included. Do bear with the long post :)
We are currently trying to model a large sewer network with potentially thousands of incoming sewer flows. Previously the generation of plan and profile...
Hi, i have a question about air valves.
Would somebody explain to me the difference between the large orifice air valve and the small orifice air valve.
I understand that the large orifice is meant to allow high volumes of air and water to enter the pipe. However, why is a smaller orifice air...
