Slot drain has the ability to handle high capacity drainage and has proven itself successful in hundreds of installations.
Trench drain flow capacity.
Q flow capacity in cubic feet per second c orifice coefficient a open area of grate ft 2 g acceleration due to gravity 32 2ft sec 2 d depth of water over grate in feet.
Hydro is a purpose written hydraulic design program modelled on differential calculus for non uniform flow in open channels.
Polymer concrete systems.
Let a cross sectional area of the trench drain in square feet.
Overall the flow rate depends on the width of the slot opening.
A is the cross sectional area of the trench drain in square feet.
For trench drains 200mm to 300mm wide test block is 10 long by 6 wide.
For trench drains less than 200mm wide test block for load testing is 10 long by 3 wide.
Concrete forming systems 0 013.
Aco can provide accurate channel recommendations with its proprietary software.
The slope can also be customized to increase flow or to overcome adverse site slope.
Permitted trench location 3.
Search by application capacity and load requirements.
Aco drain systems are available in 2 4 8 and 12 internal widths and are available with a up to 130 ft 40m of built in continuous slope.
Durable and proven channel and trench drain systems to manage sheet flow drainage in applications ranging from light foot to heavy vehicular traffic.
Let n the coefficient of friction of the trench drain body.
Our orifice equation is originally derived from the following equation.
Askaco to propose the correct size drain for your next project.
Channel flow capacity qc.
Hydraulics flow rate and slope tables can help you identify the pre sloped or neutral configiration your system needs.
There is also a trench drain calculator spreadsheet attached that can help with trench drain design.
Qc a 1 49 n r 2 3 s 1 2.
If the site does not have slope a sloped drainage system can provide it.
Using the flow rate find the appropriate width of trench that will carry the flow in a desired depth.
Unlike some other trench drain systems it s fairly easy to figure out how much liquid a slot drain can.
For trench drains over 300mm the test block is 10 diameter.
Aco drain systems consist of manufactured modular trench drains made from stainless steel corrosion resistant polymer concrete or fiberglass together with grates from a variety of materials for all loading applications.
Flow path disruptions restrictions and concentrators 2.
You can also use the attached trench drain.
Now it is time to calculate the channel flow capacity to determine what size trench may be required for your application.
The trench drain capacity calculations should first be done to determine the required flow rate.
Formulas to calculate slot drain flow rate.
