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.
Trench drain flow capacity.
For trench drains over 300mm the test block is 10 diameter.
If the site does not have slope a sloped drainage system can provide it.
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.
Overall the flow rate depends on the width of the slot opening.
Channel drain trench drain systems from nds are durable.
The trench drain capacity calculations should first be done to determine the required flow rate.
For trench drains less than 200mm wide test block for load testing is 10 long by 3 wide.
You can also use the attached trench drain.
For trench drains 200mm to 300mm wide test block is 10 long by 6 wide.

A is the cross sectional area of the trench drain in square feet.
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.
Aco can provide accurate channel recommendations with its proprietary software.
Flow path disruptions restrictions and concentrators 2.
Now it is time to calculate the channel flow capacity to determine what size trench may be required for your application.
The slope can also be customized to increase flow or to overcome adverse site slope.
Durable and proven channel and trench drain systems to manage sheet flow drainage in applications ranging from light foot to heavy vehicular traffic.
This ensures that the full force of the test load is directed onto the grate.
Let a cross sectional area of the trench drain in square feet.
Site contours site slopes can also be used to increase the conveyance capacity of the trench.
Permitted trench location 3.
Our orifice equation is originally derived from the following equation.
Using the flow rate find the appropriate width of trench that will carry the flow in a desired depth.
