HomeMy WebLinkAbout1180659 Summary Attn: Kaila Dehann Subject: FPR MRO Hangar 6/25/2018 Dear Ms. Dehann, The attached documentation is in regards to your request for hydraulic analysis for the FPR MRO Hangar project. The attached hydraulic calculations are for the S300K system with a slotted ductile iron grate. The software that ACO Polymer Products uses to calculate channel hydraulics is called “HYDRO” and is based on the principles of spatially varied flow (steady, non-uniform flow). This is non-uniform flow which accounts for liquid being carried in a trench plus the constant addition of liquid collected through the grates along the trench run, called lateral inflow. Lateral inflow is measured in gallons per minute per foot (liters per second per meter). In some situations, a Manning’s equation for open channels may also be used. The basis of the design was to capture and discharge 1600gpm and to minimize the trench drain length. The first thing to look at was the outlet capacity. An 8” sch. 40 pipe out of the SK3-040 channel can discharge 966pgm. Ending in this channel will require 2 total outlets on the run. The next step is to analyze the grate intake. A perpendicular approach slope of 1% was used as a worst case scenario, and the results show a lateral inflow rate of 147.1gpm/ft. 1600gpm over 1471.gpm/ft yields a minimum required length of 11ft. Finally, the channels themselves were analyzed. Each of the runs is capable of 2297gpm. This leaves extra capacity for each run. The limiting factor is the outlet itself. A shorter system can be used, but the idea with trench drain is to capture a spread of sheet flow. If an even shorter system is needed, a 12ft system would be the bare minimum with 2 outlets. If you have any questions or concerns regarding the attached documentation please feel free to contact me. Best regards, Jason Jonke Technical Services Engineer ACO, Inc. © 2016 ACO Copyright.
