What is Lin Yue’s biggest challenge in France?
Dear Laura,
Thanks for your message. Yes, I’m having a great time on my student exchange program in France. I was a bit nervous before I arrived here but there was no reason to be. My host family is really nice. They go out of their way to make me feel at home. The grandmother knows that I miss Chinese food a lot. So she actually learned how to make Chinese food! She also has a teenage granddaughter about my age. She’s really kind and she always talks to me in French to help me practice. You wouldn’t believe how quickly my French has improved because of that. I’m very comfortable speaking French now. Although I still make lots of mistakes, it doesn’t worry me like it used to. My biggest challenge is learning how to behave at the dinner table. As you can imagine, things are very different from the way they are at home. For example, you’re not supposed to put your bread on your plate. You’re supposed to put it on the table! I thought that was pretty strange at first, but now I’m used to it. Another example is that you’re not supposed to eat anything with your hands except bread, not even fruit. You have to cut it up and eat it with a fork. Another thing is it’s impolite to say that you’re full. If you don’t want any more food, you should just say, “That was delicious.” Also, you’re not supposed to put your elbows on the table. I have to say that I find it difficult to remember everything, but I’m gradually getting used to it. I don’t find French customs so strange anymore.

公式中λRe 35.9很小，可以忽略，故λ1＝1.14－2lg dε代入ε/d=1.67×10-3 即λ=0.022 ∴h f1＝λd lgv22＝0.022×150×1 2/0.3×2×9.8=0.56m二、管件阻力：（管件、阀门等）h f2名称 数量 单项阻力系数标准弯头90° 10只 ζ1＝0.75（查附表2） 弯管120° 2套 ζ2＝0.2（查附表2） 标准三通管 3只 ζ3＝1.5（查附表2） 闸阀 4只 ζ4＝0.17（查附表2） 止回阀（摇板式） 2只 ζ5＝2 （查附表2） 蝶阀 （45°） 1只 ζ6＝18.7（查附表2） 法兰 16只 ζ7＝0.25（经验值） 变径管 2只 ζ8＝0.25（经验值） 喇叭口 1只 ζ9＝0.25（经验值）h f2=ζgv22=（ζ1+ζ2+ζ3+ζ4+ζ5+ζ6+ζ7+ζ8+ζ9）gv22=(0.75×10+0.2×2+1.5×3+0.17×4+2×2+18.7×1+0.25×16+0.25×2+0.25×1)×12/2×9.8 =2.07m三、进出口局部阻力h f3突然扩大：ζ＝222211⎪⎪⎭⎫ ⎝⎛-d d 由于d1/d 2≈0，所以ζ＝1h f3＝ζgv22=gv22=0.05m四、管网总阻力h fh f ＝h f1+h f2+h f3＝0.56+2.07+0.05＝2.67m 所以H= h f + P d －P s =2.67 m 取修正系数为1.20则H 0=1.25H=1.2×2.67=3.2m ＜D －S=8m 故回水势能满足跃过凉水塔的要求。
