一、虹吸原理虹吸原理:图1为虹吸现象物理原理图。加在密闭容器里液体上的压强处处相等。而虹吸管里灌满水,没有气,来水端水位高,出水口用手掌或其他物体封闭住。此时管内压强处处相等。一切安置好后,打开出水口,虽然两边的大气压相等,但是来水端的水位高、压强大,推动来水不断流出出水口。虹吸 First, the siphon principle Siphon principle: Figure 1 for the siphon phenomenon physical principle diagram. The pressure on the liquid in the closed container is equal everywhere. The siphon filled with water, no gas, incoming water level is high, the outlet closed with the palm of your hand or other objects. At this time the same pressure inside the tube. After everything is settled, open the water outlet, although the atmospheric pressure on both sides of the same, but the incoming water level is high, pressure, and promote continuous outflow of water outlet.
