Good information Slight correction that it's not the capillary action which makes the water to reach the top of the tree, as the xylum tubes can rise only 1m with the given diameter. So it's the negative pressures that it is being created at the leaves when it evaporates and also the continuous column of xylumn tubes which are filled with water from the beginning without presence of any air bubbles.
Anthony Tovar I think as my teacher told me is that when the weight of the water in the strew becomes equal to its surface tension force that’s acting upward, the water level stops from flowing. that’s why as a narrower the strew is, the level of water is higher.
If you blow through a star with a big opening on either end the wind on the other side will be weak, if the straw has small openings then the wind tends to be stronger. That's the basic idea.
The height of the water is defined by when the capillary forces (i.e., the adhesive forces described in the video) balance the gravitational pull on the water. The capillary forces are proportional to the circumference of the tube. The weight of the water is governed by the volume of water that is pulled up the tube, which is proportional to the cross-sectional area of the tube. The ratio of the circumference to the cross-sectional area is 2*pi*r / pi r-squared. As r gets small, this ratio becomes large. As r gets big, the ratio becomes small (i.e., at infinite radius, the ratio goes to zero).
I think it would rise, but not as high. Without a blind end, the height to which the water rises is governed by the when the force of gravity acting on the water column balances the capillary pressure (which arise from the adhesive forces described in the video). With a blind end, as the water rises (due to the capillary pressure), the gas in the tube would become compressed, and the resulting increase in air pressure would also act to limit the height to which the water rises, in addition to gravity.
This #Physics video shows a very fascinating - and important, phenomenon. #Capillarity ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PP9mn-X9i2Q.htmla
We people - Studying Physics . . . That salamander in the beaker to this guy's right on shelf listening to all the shit he can't understand but has to listen 'cause what else can he do?? . . . Maybe a she, I'm not gender biased...
