    Default water tank

    I need to fab. a 4' wide by 5' tall by 3' deep tank to hold water. This tank will be mounted inside a box truck for supply to a concrete cutting saw on site.

    My question is, what material ( I am assuming 6061) and what thickness do I need.
    I do plan on at least one baffle, maybe for support on long side as well as slosh dampening.

    ANY info is greatly appreciated
    Thanks,.

    If it's going in the back of a work truck I would use 1/8" 6061. If you went any thinner there is a good chance of punching a hole in it. and yes add a baffle or 2 to help support the long wall section of the tank and sloshing when it's full.

    With 3,744 pounds of water, I would definitely go with two baffles minimum! You may want to consider ringing, (at least the middle) of the tank with angle or C-channel.

    I think i would follow Sonoras baffle/ring advice and use 1/4" material. By my calculations you would need an excessive amount of stiffeners on 1/8". (assuming i did the calculations right )

    Probably more like 450 gallons (if completely full) approx 3735#.

    How about a plastic water tank instead?

    Northern Tools (among other suppliers) have an assortment of tanks around the $300 range.

    Many concrete coring and cutting companies have plastic tanks mounted on the trailer they carry their saws on.

    Just a suggestion

    4’ x 5’ x 3’ x 7.48 = 448.8 gallons

    4’ x 5’ x 3’ = 60 cubic feet.

    Pure water weighs 62.4 pounds per cubic foot.
    Gallon of pure water weighs 8.34 pounds.

    You're reading from page 638 of Thomas J Glover's Pocket Reference, I see.

    If a gallon of water weighs 8.333#, and a cubic foot of water contains 7.5 gallons, and a cubic foot of fresh water weighs 62.4#, which is heavier, a pound of steel or a pound of aluminum?

    I'd say, a pound of coffee

    Oh my Gawd, everybody knows a pound of steel is heavier than a pound of aluminum!
