[認真] 很X化話工導論

[yanhanwang (jessie)]

化工導論到目前為止都還是一樣很廢

再加上大家都說話導的成績是亂數的

所以 超想翹課的~

但是,昨天突然覺得老師可能會點名 就乖乖去上課了

沒想到 老師最後發了一張作業 下禮拜要交

但因為份數不夠 所以我只多拿了一張

想要印的話可以找我或詹皓安

題目如下:

(一) A wet paper pulp is found to contain  71% waterby weight.

After drying, it is found that 60% of the original water has been removed.

Calculae the following:

  (a)The composition of the dried pulp
  (b)The mass of water removed per kilogram of wet pulp.


(二) The Sun-moon Lake can be visualized as a large cylindrical tank with

1000m in diameter and 10m in depth. The water flowing into the lake

is at a rate of 10000Kg/s and contains 1g NaCl/Kg of water.

If pure water is evaporated on the surface at 5g/sm^2 ,

what is the rate of water flowing out of the lake and its composition

if it is to maintain at steady state?


對了,我問了化工系班代,他說他沒有考古題,也沒聽別人討論過考古題

而且問了另一個化工系的同學,不過他也說他不知道~ 超怪的~~

不過他會幫我們問一下  就降~
