小安在学习了《流体的流速与压强的关系》这节课之后很兴奋,老师让体验的那些实验太有趣了,会跳高的硬币、飞机的机翼、飞舞的泡沫等,回家后他又挨个实验了一遍。可是小安仔细一想,流体既包括气体也包括液体,而这些实验都是关于气体的,难道液体就没有这样制作简单、现象明显的实验吗?想到这里,他 After learning the lesson about the relationship between fluid flow rate and pressure, Xiaoan was very excited. The experiments that the teacher had to experiment with were so interesting that he would jump high coins, the wings of the aircraft, the foam of flying, One by one experiment again. But Xiao An careful thought, the fluid includes both gas and liquid, and these experiments are about the gas, is the liquid there is no such simple, obvious phenomenon experiment? Think of here, he
