Re: unloading a tank car through the bottom valve

Via truck, pumped into above-ground horizontal storage tanks. I don't think
Coriolus forces were involved. Tom Madden

Coriolis is always there. Everything on earth at higher latitudes is moving
more slowly than at lower latitudes, relative to a fixed point in space. This
differential rotation induces a clockwise movement in the northern hemisphere
and counter-clockwise in the southern hemisphere. But it doesn't affect water
in toilets, or above-ground horizontal oil storage tanks. But if you could build
a 1,000 mile long frictionless turntable loaded with freight cars, then it would
start rotating all by itself, unless the pivot point was exactly on the equator.
Phew, just barely got back on topic!
