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~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.193.48
