This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1882 Excerpt: ...by applying the mouth to the end B, after the other arm of the siphon has been put into the vessel of water, or by filling the siphon with water before it is placed in the vessel. The water will flow through the siphon from C to B until the vessel is emptied, or until the level of the water falls below the mouth of the arm in the vessel. The flow of the liquid through the siphon seems opposed to the well-known fact that water will not run up hill; but it will be seen that the water is really flowing from a higher level C to a lower level B. If we consider the water in the siphon at M, we see that the force which acts upon it from left to right is equal to the pressure of the atmosphere minus the pressure of the water in the tube from Mto C, whose depth is DC; and the pressure which acts upon it from right to left is equal to the pressure of the atmosphere minus the pressure of the water in the tube from M to B, whose depth is A B. Since AB is greater than DC, the pressure at M towards the right will be greater than that towards the left. Consequently the water at M moves on towards B; and, as it moves away, more water is driven up into the arm CM to take its place, by the pressure of the atmosphere on the surface of the water in the vessel. No liquid will flow through a siphon unless the atmospheric pressure is sufficient to raise it to the bend of the tube. 95. Tantalus's Cup.--This is a glass cup with a siphon tube passing through the bottom, as shown in Figure 73. If water is poured into the cup, it will rise both inside and outside the siphon, until it has reached the top of the tube, when it will begin to flow out. If the water runs into the cup less rapidly than the siphon carries it out, it will sink in the cup until the shorter arm no longer dips in...
