An equation used to evaluate vacuum filtration isQ = pA2(VRw + ARf),Where Q L3/T is the filtrate volume flow rate, p F/L2 thevacuum pressure differential, A L2 the filter area, the filtrateviscosity, V L3 the filtrate volume, R L/F the sludge specificresistance, w F/L3 the weight of dry sludge per unit volume offiltrate, and Rf the specific resistance of the filter medium. Whatare the dimensions of Rf and and ?

The experimenter who does not know what he is looking for will not understand what he finds. Claude Bernard INTERNAL ANDE XTERNAL E NVIRONMENTS Homeostasis refers to…. ▯Relative stability of internal milieu…. ▯ ….as opposed to external environment ▯Dynamic process, not a static one ▯ Physiological variable fluctuates ▯ Does not remain constant ▯ ‘Balance’ does not mean unchanging ▯Glucose, water Homeostatic Control Systems ▯ In order to maintain homeostasis, control system must be able to ▯ Detect deviations from normal in the internal environment that need to be held within narrow limits ▯ Integrate this information with other relevant information ▯ Make appropriate adjustments in order to restore factor to its desired value Chapter 1 Homeostasis: The Foundation of Physiology T HE F OUNDATION OF P HYSIOLOGY "la fixité du milieu
