[認真] 很X化話工導論
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~
