Assuming: an 8 inch inside diameter, 1 gallon of water weighs 8.345404 pounds, 231 cubic inches of water to the gallon, volume of cylinder = Pi * radius^2 * height volume=3.14 * 4^2 * (4000 * 12) volume = 3.14 * 16 * 48,000 = 2,411,520 cubic inches 2,411,520 cubic inches of water when full. -------------------------------------------------------------------------- A 4000 foot cylinder/pipe with an 8 inch inside diameter, if full of water, will contain 10,439.48 gallons of water weighing a total of 87,121.68 pounds or 43.56 tons.

### How many cubic meters of dry sand in 1 acre if the depth is 8 feet?

1 acre is approx 4000 sq m
8 ft is about 2.4 m.
so 1 acre at 8 ft depth = 4000* 2.4= 9600 cu meter
===========================
1 acre = 43,560 square feet
Volume = 43,560 x 8 = 348,480 cubic feet = 9,867.9 cubic
meters (rounded)
Note: That's the volume of 1 acre 8 feet deep, whether
it's empty, or full of sand,
mud, water, or old newspapers.

### How much does 100 cubic feet weight?

It all depends on what you have in the cubic feet.
-- If the cubic feet are full of air, they weigh about 8
pounds.
-- If they're full of water, they weight about 6,243 pounds (3.1
tons).
-- If they're full of lead, they weigh about 70,793 pounds (35.4
tons).

### How do you build a model dam?

For static purposes, this is not a difficult task, for
the equations relating the model to the full sized dam are
linear.
However, when dynamic behaviour is considered, then the
relationship between model and full-size is not linear. Effects
such as fluid flow - water hammer, and fluid oscillation must all
be carefully understood.
But maybe you just want to make a model of a Beaver dam!
