Jerry/MT said: (quoted from post at 10:49:15 08/09/08) Atmospheric pressure( 14.7 psia +/-) will hold up a column of water ~33ft+/- high. Just do a free body diagram of the forces on the water and you"ll be able to understand it.
The pressure on the bottom of the waterer is just the density (or specific weight) times the height; 62.4 lb/cu ft X the height of the container. That has to be greater equal atmospheric pressure to cause the water to flow out. So,
62.4 x H = (14.7 x 144)
H = 2116.8/62.4 = 33.9 ft.
So 14.7 psia will hold up a water column of 33.9 ft. anyhigher and the water runss out until the column is 33.9 ft again.
uh huh riiiiggghhhhhhtttttt gotcha , right up to free body
