在日常生活中,我们经常可以看到这样一些现象:往塑料瓶或塑料袋中注满水,如果侧壁上有孔眼便会有水流喷出,那么,水流喷射距离的远近和哪些因素有关呢?针对这个问题,我做了一系列的实验和探究。一、液体密度对喷射距离的影响取3支大小相同的塑料瓶,用大头针在距瓶底相同高度处分别插入,然后,往3支瓶中分别注满清水、10%的食盐水和饱和食盐水,并放置在同一水平面上,以水 In daily life, we can often see such phenomena: When filling plastic or plastic bags with water, if there are holes in the side walls, water will be ejected. Then, what is the distance between the jets and the distance between them? For this issue, I did a series of experiments and explorations. First, the impact of the liquid density on the spray distance Take three plastic bottles of the same size, insert them at the same height from the bottom of the bottle with a pin, and then fill the three bottles with clean water, 10% saline, and saturated salt. Water and place it on the same level with water
