Simple programm written in a QuickBasic language and compiled in FreeBASIC, which allows you to verify an horizontal grit chamber. Once you have put the geometric section and the incoming flow, it computes using elementary formulation the shorter length of this hydraulic device.
The horizontal_grit_chamber.bas bases itself on the previous article: Horizontal grit chamber: theory. It can not be considered a correct and rigouros method to design these devices, but an help to verify the assumptions made during the plan phase.
The program with source code and binaries (compiled for Windows XP and Ubuntu 12.04) is available here: horizontal_grit_chamber.zip
- Q = 31 l/s (flow rate coming in);
- B = 1.25 m (width of useful sedimentation volume);
- H = 1.00 m (height of useful sedimentation volume, shorter than the real one);
- Ltot = 1.80 m (total length of the chamber, verified only if the program outputs a smaller value).
