My question is about specific gravity of flowing water.
(OP)
If one cubic foot of river water at 62.4 lbs. is moving 5 ft per second at the surface of a river is moving 312 lbs per second, is one cubic foot of river water between 9 & 10 feet below the surface moving 3120 lbs. per second???

Thank You FeX32.
I was referring to simple 16 ounces per pound weight.
I am aware that moving "mass" is derived by converting to "slugs" or 32.174 lbs. per "slug", if this old mans understand in of Newton's thingy is correct.

RE: My question is about specific gravity of flowing water.
The best way to answer the question in my view would simply be to state that if the water moves at 312lbm/sec at the surface it has precisely the same 312lbm/sec 10 feet below assuming a linear and flat velocity profile.
Gravitational attraction is negligible for these purposes.
And compressibility is negligible for water.
Now if we were talking about the atmosphere 10000km up and at the surface we would come to a different conclusion.

RE: My question is about specific gravity of flowing water.
At normal pressures water is incompressible, so density at 10 feet does not change due to pressure. Although hydrostatic pressure does change directly with increasing depth to approx. 4 psi at 10 feet.

No really, maybe we should be talking about Mars.
