1.節(jié)水常識 中、英文版
1、浴室如何節(jié)約用水？ 不要把煙灰、剩飯、廢紙等倒進馬桶用水沖。
安裝一個貯水量小的抽水馬桶。這樣每沖一次水可節(jié)省5-7公斤水。
淋浴器安裝節(jié)水龍頭，選擇較短，不用太長水管的淋浴器。 經(jīng)常檢查自來水管的水龍頭和水管，看看是否漏水。
即使是漏一小滴水，一個月就白白流掉1500公斤。 2、廚房和洗衣間如何節(jié)約用水？ 只有在自動洗碗機里裝滿要洗的器皿時才使用。
自動洗衣機也是如此。 洗蔬菜時不要一直開大水龍頭，而是先在清水槽中洗干凈再用水沖洗一遍。
如果不用洗碗機清洗盤、碗，也不應直接用水沖洗。把要洗的食具先放入一個水槽洗凈后，再放入另一個水槽快速沖洗。
3、室外如何節(jié)約用水？ 只在需要澆水時才給草坪澆水?？梢韵日镜讲萜荷?，如果抬起腳后，草能自然伸直，說明尚不需澆水。
天氣涼爽時澆水，清晨為澆水的最佳時間。 把灑水裝置直接安裝到草坪上，這樣灑出的水也可直接澆到草坪上。
種植抗干旱的草或樹木，并在樹木或植物周圍培一層護根的土，以減少水份蒸發(fā)。 應該擦洗汽車，而不是用水管沖洗后再擦。
4、家庭節(jié)水的主要方法有哪些？ 一是使用水沖廁所的家庭，可在水箱內放置1-2塊磚，以減少排水量，達到節(jié)水的目的。 二是少用洗衣機，因為用洗衣機洗衣服要比手工洗衣服耗水量多一倍。
為節(jié)約用水，除被子、床單等大件用洗衣機洗，其他小件衣服用手工洗為好。 三是采取綜合利用、一水多用的辦法節(jié)水。
如淘米水可用來澆花；洗臉水可用來洗衣或洗腳。 5、家庭節(jié)水應注意哪些事項？ 及時關緊正在滴水的水龍頭。
在廁所蓄水箱里裝一個節(jié)水裝置。 不要在中午澆花，因為中午陽光強，水易蒸發(fā)。
在水龍頭上裝個流水控制器，可以節(jié)約大量用水。 告訴全家成員，在洗蔬果、洗手絹、刮胡子時，不應讓水龍頭開著。
在你家水龍頭處寫上“請注意節(jié)約用水”。 停電停水后，當你外出時請擰緊水龍頭。

6.一篇關于水的作用的英語作文
Water is essential to living things. For instance, if there is no enough water in a human body, a person may feel uncomfortable or get sick easily. To make matters worse, one may die of thirst. Similarly, plants may wither or die for lack of water. It is apparent that all living things need water to keep alive.
Judging from the importance of water, we should know how to conserve water. The first thing is to stop polluting water because what we really need is clean water. At the same time, be sure to turn off the faucet immediately after using water. And we should make efficient use of water to avoid wasting it. One way is to recycle as much water as possible. To sum up, we should economize on water so as to maintain the abundance of water, which is an indispensable element of life.
水對生存事是根本的。 例如，如果沒有在人體的足夠的水，人也許感到難受或容易地病。 要使事態(tài)更壞，一個也許死于干渴。 同樣，植物也許凋枯或死因缺乏水。 是明顯的所有生存事需要水保持活。 從水判斷的重要性，我們應該會保存水。 第一件事是停止污染水，因為什么我們真正地需要是清水。 同時，請務必關閉在使用水之后的龍頭。 并且我們應該做高效率的用途水避免浪費它。 一種方式將回收同樣多水盡可能。 要總結，我們在水應該節(jié)約以便維護水豐盈，是生活的一個不可缺少的元素。
7.簡單的流體學知識,英文版這是一個有關水流為什么在窄的地方流速
speed of water 是水的速度，rate of flow 是流量，水的速度是用m/s來定義的.流量是用m^3/s來定義的.它們之間的關系時 流量=水速*管子的截面積其實你說的是伯努利方程（Bernoulli equation） 流體力學中的物理方程（p/ρg）+(v^2/2g)+h=常量 （p是管子中任何一點的壓強，h是管道中任何一點與參考平面的高度，ρ是密度，g是重力加速度）對于一個管子來說，設有A,B兩點，那么A,B兩點的高度差是確定的，所以（p/ρg）+(v^2/2g)=常量-h等式的右端為一個常量，所以p大的時候，v就減小，p小的時候，v就增大.“窄的地方流速快，寬的地方流速慢”對于這個問題，很好理解，假設管子內有水在流動，設在窄的地方的截面積為S1，寬的地方的截面積為S2，設單位時間內有體積為M的水流入管子，由于水是不可壓縮的，所以在窄的地方流速為M/S1，寬的地方為M/S2，顯然M/S1>M/S2.。
