Also, can't seem to find much information on the linear grate linear drain from ACO except for the following:
It states that the Intake sq. in. = 55.38 which is 60% more than the next nearest grate style "Flag". Cannot find any spec on "Linear" grate flow rate and I would assume that it would get more than the Flag based on a higher intake. Looking at a chart they have in their technical manual for flow rates at 0" head:
No grate = 6.65 usgpm
Tile = 6.49 usgpm (makes sense that it would be less given that it has blocked off some of the intake area with tile)
Flag = 6.34 usgpm
Now this is where I get confused. Flag has intake sq. in. = 31.36 while Tile has intake sq. in. = 18.10. Wouldn't you think the one with the larger intake area would be able to process more flow?
Now trying to estimate flow for the linear grate which is not shown and it has intake sq. in. = 55.38.
So either this is not the intake opening of the grate or something is not correct.
All these numbers come from page 16 of the technical manual:
Can anyone clarfiy? Thanks,
