Project calls for widening a 1.5 m (5') concrete sidewalk to a 3 m (10') wide asphalt multi-use trail (pedestrians and cyclists). Owner wants to keep existing concrete sidewalk in-tact and black top over it. We are thinking of using 100 mm (4") of compacted granulars over the existing concrete...
Yes, drainage is collected around foundation and seepage from surface runoff. Soils can be classified as well graded gravel with about 15 to 20% silt. Soil percolation at the deths required would be slow. Slopes away from the foundation would be considered fair. No surface water flowing...
We have a situation whereby we cannot connect a large residential dwelling storm sewer service (weeping tile drainage) to the existing storm sewer main in the street. The Municipality is allowing us to drain to a rock soak-away pit on the property. We are trying to size this soak-away (depth...
I'm interested in designing the base as a foundation. I will be using 30 MPa concrete delivered to the job site. I need to design the diameter and depth of the pier and the footing. I know that I have to check the strucutal aspects of sliding, overturning and shear. The pole being attached...
I am trying to find a good reference text for concrete pole base design (for parking lot lighting). Does anyone know of any? I'm sure the key design checks are sliding, overturning and shear.
Thanks again CountOlaf. Let me pose this question. The 6" dia. watermain has an operating pressure of 60 psi with a flow of 900 USGPM. The 60' long 3/4" copper pipe is connected to the watermain. How do I determine my flow at the outlet of the copper pipe? I know how determine the head loss...
Is there a calculation available to determine the maximum flow through 3/4" copper (type k) tubing? For example, if 60' of 3/4" copper tubing is connected to an 6" watermain, with a flow of 900 USGPM in the watermain and a static pressure of 60 psi, what is the maximum flow rate through the...
