Σελίδα 354 - ... have, in the short branch, a quantity of air separated from the external air, and at the same pressure. Mercury is then poured into the long branch, so as to reduce the volume of this inclosed air by one-half; it will then be found that the difference of level of the mercury in the two branches is equal to the height of the barometer at the time of the experiment; the compressed air therefore exerts a pressure equal to that of two atmospheres. If more mercury be poured in so as to reduce the...
Σελίδα 416 - Here, too, we drop the consideration of friction and the weight of the piston. 536. The velocity of the water flowing from the sucking pipe into the barrel should be equal to the velocity with which the piston moves. For if it be greater, less work will be done than the pump is competent to effect; and if it be less, a vacuum will be produced below the piston, which will therefore be moved upwards with great difficulty. If v be the velocity of the water in the sucking pipe, d the diameter of that...
Σελίδα 388 - ... water. A body in motion appears to be resisted by a stagnant fluid, because it is a law of mechanical nature that force must be employed in order to put any body in motion. Now, the body cannot move forward without putting the contiguous fluid in motion, and force must be employed for producing this motion.
Σελίδα 359 - If this is so it is seen that air is being depleted from that part of the pattern between the ridge line AB and the trough line CD while it is accumulating between CD and EF. There is consequently divergence to the...
