Hey all,
I am currently undertaking a sewer system design using the Windes Programme. I can use the simplier parts such as the storage design and the system design. However i seem to be having problems when i bring the whole lot into simulation. Nothing seems to be linking up. I have a system...
Yes cvg. I definitely take your argument about the runoff during the 100 year storm. I think myself that the Tank should be sized to allow a min amount of backup - ie the storage in the granular fill. Thanks for the help
I have been told to conservatively to ignore infiltration under the permeable pavement. Yes the tank has an outflow into a main sewer with flow limited to 5 l/sec using a hydrobrake. The pavement is a precast slab 1m * 3m with slots between to allow for drainage. Underneath is 50mm of clean...
Hi all
I am currently trying to design an attenuation tank with a permeable paving area for a 100 year storm with a max volumn of 501m3 as required by the client on the job. All drainage initially runs to the attenuation tank. I have sized my tank at 144m3. The plan area of the pavement area is...
Have been looking at all those books and thanks for all your information. Just wondering is that Wang & Salmon book metric or imperial or can a copy of both be obtained.
Hey all
I have just graduated and have started designing some concrete members which i am not fully familiar with attenuation tanks etc. I was just wondering could anybody recommend the best concrete design book to me to offer me some clear and suitable guidance when designing concrete members...
Hey all
I seem to be having some problems converting Imperical units to metric as i am a uk engineer. The problem is to do with Shear in a flat slab.
Allowable Vc=4*sqrt(Fc)*bo*dv
Imperical Units
Vn=102,000lb
fc=4000psi
bo=83in
And the imperical depth for the slab is given as 4.86in
Mertic...
