Problem 6.40

An important parameter in the design of gas absorbers is the ratio of the flow rate of the feed liquid to that of the feed gas. The lower the value of this ratio, the lower the cost of the solvent required to process a given quantity of gas but the taller the absorber must be to achieve a specified separation.

Step-by-Step Solution:
Step 1 of 3

Lecture 23 3/9/2016 Sleep and mood  Bidirectional relationships between sleep and mood o Mood is not great, sleep problems often follow o Sleep is not great, mood may be more irritable  one way to regulate mood is to get your sleep on track  quality versus quantity o sleep quality is very important  it was believes for a while that you are either sleep or awake o now know that sleep is a lot of physiological functions: different stages of sleep  stages of sleep o stage 1- barely below the threshold of consciousness:  brain is still very active (car horn can wake you up and you don’t realize you were asleep)  only a few minutes o stage 2- middle stage  Body and brain are both starting to slow down. o stage 3- delta sleep - deepest. Brain is almost completely dominated by delta waves  Combined stage 3 and 4 because they were more similar than different  Body does not want to wake up  Good for memory  Very important for the body to physically prepare itself o REM: rapid eye movement  Very shallow state of sleep  Brain is dreaming in this stage  Brain is as active as when you are fully awake  Body is naturally paralyzed  Stage 1-3 + REM = one cycle of cycle o 90 minutes o Get through multiple cycles in the night  Helps: to fall asleep, stay asleep o Stress o Medicines: can help or hinder o Light stack that may be good for sleep: crackers, bread, tea, anything that will make your relax  Hinders: o Caffeine: may be stuck in stage 1 o and stage 3 o Medicines o Sugar late at night is bad  You will sleep easiest if you go to sleep and wake up around the same time everyday  Look at tablet, phone, TV: body and brain don’t know how to process the light: o Brain interprets the light as sun o Books are very good  Don’t think about stressful thoughts as you’re about to fall asleep  How long should you lay awake in bed trying to fall asleep o More than 20 minutes: get out of bed and do something else  Sleep-hygene: getting sleep back on track and treating sleep disorders
