今天中午,我和妈妈一起做了一个小实验。我们往一个纸杯里注满了水,又用大头针在杯底下扎了一个小洞,再让水慢慢地漏在一个小箱子里,并计算漏完一杯水需要多长时间,目的是为了算出这杯水的漏水速度。如果一个没关紧的水龙头和这杯水的漏水速度一样,那么,我们就知道在一定时间内要漏多少水。下面是我们的实验记录:(1)漏完一杯水用(20)分钟。(2)如果一个关不紧的水龙头的漏水的速度和这个漏水速度相同,那么: Today, noon, I and my mother did a little experiment. We filled a paper cup with water and pinned a small hole under the cup with a pin to let the water slowly drain into a small box and calculate how long it would take to drain a glass of water Glass of water leakage rate. If an unimportant faucet is the same as the water leaked in this glass, then we know how much water to drain in a given period of time. Here is our experimental record: (1) drain a glass of water (20) minutes. (2) If a tight water tap leaks at the same rate as this water leak, then:
