A 10-m-long, 5.042-cm I.D. copper pipe has two fully opengate valves, a swing check valve, and a sudden enlargement to a9.919-cm I.D. copper pipe. The 9.919 cm copper pipe is 5.0 mlong and then has a sudden contraction to another 5.042-cm copperpipe. Find the head loss for a 20 C water flow rate of 0.05 m3/s.
Biology Lecture Notes To multiply, add exponents To divide, subtract exponents Dissociations: examples: Assume those are full dissociations Strong Acids 1.0mM HCl 1.0mM H + 1.0mM Cl + Strong Base 1.0mM NaOH 1.0mM Na + 1.0mM OH Ionic 1.0mM NaCl 1.0mM Na + 1.0mM Cl HCL is a strong acid it fully ionizes in water this lowers the pH NaOH is a strong base It accepts H this raises the pH Weak acids ex: water, Not all the acid molecules dissociates into ions pH: pH is way to express [H ] [H+] means concentration of hydrogen ions, also called protons pH= log [H+] As [H ] goes up, the pH goes down + As [H ] g
