在流动的液体中,压强跟流速有关．流速越大,压强越小；流速越小,压强越大．利用这一原理,可以解释下面一组实验现象．1．跳动的硬币
In flowing liquids, the pressure is related to the flow rate. The greater the velocity, the lower the pressure; the smaller the velocity, the greater the pressure. Using this principle, the following set of experimental phenomena can be explained. 1. Beating coins
