Liquid Capacity of Gravel Fill
Liquid Capacity of Gravel Fill
(OP)
What is a good rule of thumb for the available liquid volume in a fill of clean 57 stone?
Thanks!

Liquid Capacity of Gravel Fill

RE: Liquid Capacity of Gravel Fill
Vstore = (Vtrench * n)/F.S.
where:
Vstore = storage available in stone filled trench
Vtrench = volume of trench (based on gross dimensions)
n = porosity of stone fill (for 20-25mm stone a value of 0.40 is reasonable)
F.S. = Factor of safety...say 1.15 (15%)
Hope this helps some.

You could build a one cubic foot box, fill it with your stone sample and then pour in water. Measure the water as it goes in. Your solution for your stone and you can save the box to test other stone. There may be a cheaper gradation in your vacinity.

100% passing a 1 1/2 sieve
95 to 100% passing a 1 in. sieve.
25 to 60% passing a 1/2 in. sieve.
0 to 10% passing a #4 sieve.
0 to 5% passing a #8 sieve.
I wouldn't expect something with such an even gradation to be really good for holding liquid. But if that is what you have, you're stuck.

100% passing 2"
75% passing 1 1/2"
50% passing 1"
25% passing 3/4"
10% passing 1/2"
0 passing #4
The small particles will plug the drain.
