There are so many approaches to it but lets look at 2 of them: 1-proportion your foundation members such as the floor beams, the footing(strip or pad)etc. so that the bearing pressure is within 2500 psf. If you keep within this limit, the settlement should be with that allowed. You can calculate...

I have a project in which I'm to study a river course with the aim of identifying the source pollutants coming from a group of wastewater treatment plants and also to study the effect of the pollutant on the groundwater sources along the river's catchments basin. It would be most appreciated if...

Your best option is to provide a sedimentation tank or grit accumulator within or outside the wetwell. Trying to pump the grit along with the wastewater will cause you more problems than will be necessay.

If you can forecaste the worst condition(ie Qmax may be for the 100year flood), then use any hydraulic equation to solve for the depth in the channel. You can also vary your Q and get the relevant discharge heights(elevations). Test drive stormnet as to be able to forcaste the 100year storm. you...

I do not understand why you are going through all these rough paths. Do you want to reinvent the wheels?(no offence meant). Down load stormnet, go through the manual and you will find the lead to the sites that will give you all the informations that you needed to complete that...

Why don't you build a defence wall between the property and the offending adjacent side to the property (as to ward-off the overland flow or inflow/infiltation particularily from the street which floods from the Hackensack River.). Then calculate the resultant run-off for the enclosed area(the...

Use SWMM5. It will solve this for you as fast as possible, without any compications or doubts. It is very easy to learn and use as it has a very good GUI. Good luck Teddy

I compiled this Excel program as to help me in the design of wet-well and pumps. Can someone check if there is something that I missed out and also tell me how to animate the program so that when less than the number of the pumps shown on the diagram are required(like when 2 pumps are required...

I do not follow with your suggestion that I should insert a storage unit and a pump to represent the wet well and siphon. I do not understand how to position them as such will be grateful if you should give me a sketch. I had already concluded the design using manual calculations but I want to...

You had a good start by determining the average flow and calculating the max flow as approx 2 x average flow. Volume of your wet well should be V =(max discharge x T)/4. Do not oversize the well as this will lead to stagnation of liquame, oil etc and lead to putrification in the wet well that...

Convert 10,000 gallons to cubic feet(using the freely available unit converters. You can google and download one from the web). If you have decided to use a surface area of 4000 SQ FT(given some engineering considerations and your constraints), then simply divide the volume resultant from your...

I did not mean to sing someone's praises but it is hard for me to hide my feeling. After reading the reference in the lead-http://smig.usgs.gov/SMIG/features_0398/runoff.html posted by tsgrue, I felt that this article is whort everyone's reading as to be fully informed and equiped to the fact...

Well it depends on you definition of overloading. But as much as I know, your definition does not go the way long. Overloading could be as result of anything, including the loading from wind etc. The much that we can do is to make informed estimates of loads that are imposed on structures. we...

Remember that resonance Occurs when a body is oscillating in harmony with a body that is supporting it. The wave form of the harmonic motion has equal spacing of crests and troughs. So the random spacing will not allow the supported body to attain this state as crests and troughs will occur at...

Also view the following attachment. It may be different from the one sent earlier but the concept is the same.The section is as the one sent earlier(refer to the previous drawings on attachmnet...

I am sorry I could not reply much earlier. It is due to work pressure. Yes, I used divider to split the flow over the quantity admissible(revised to 75.0l/s-which is to pass through the siphon)and the excess is to be diverted through a discharge pipe that discharges into the canal. I modelled...

Please give me some thing with which I can carry out any design as such, that will not limit me to the figures listed above. Teddy

tsgrue, try this to see if you can download from the attachment(as in my last upload): Download the attachment without opening directly from the site but first save on you desktop, document or the like. After saving, then open the file as saved. I tried it and it worked Teddy

A skylight is not weightless(even air is not weightless) as such a structure that is not well supported must fail, be it for reasion of material, craftmanship or design mistake all but point to the same thing-overloading of the supporting structure. Teddy
