一、液体压强与深度的关系我们知道,液体压强的计算公式是p=ρgh.液体产生的压强大小仅跟液体的深度和密度有关,与液体的多少没有关系.对于某种液体而言,其内部深度越大,产生的压强也越大.我们在游泳或洗澡时,进入水中越深,感觉呼吸越困难,就是因为进入水中越深水的压强越大造成的.对于液体的压强随深度增加而增大,我们也可以这样理解:把液体看成是整体,液体越深,离表面越远,液体就越多,液体所受重力也就越

First, the relationship between liquid pressure and depth We know that the formula for calculating liquid pressure is p = ρgh. The magnitude of the pressure generated by the liquid is only related to the depth and density of the liquid, and has nothing to do with the amount of liquid. For a liquid, its The greater the internal depth, the greater the pressure generated.When we swim or bath, deeper into the water, feeling more difficult to breathe, because deeper water into the water pressure caused by the greater pressure on the liquid with depth And increase, we can also understand: the liquid as a whole, the deeper the liquid, the farther from the surface, the more liquid, the liquid will be the more gravity
