rho g h two, this h 2 distinguishes it from h in part A. Us now have 1.50 meter because that the elevation now, minus press of the blood. I substituted the number one through a subscript b there to say the this is the blood pressure. Climate we plug in numbers, for this reason it's 1025 kilograms per cubic meter density, times 9.81 newtons every kilogram, time 1.5 meters, minus 1066.4 pascals i m sorry is eight millimeter of mercury converted into pascals, climate times pi, times 0.15 time ten come the minus 3 meters radius of the tube to the power four, separated by eight time the viscosity the 1.002 times ten come the minus 3 pascals seconds, times two and also a half times ten to the minus 2 meters length of the tube. This functions out to 0.111 cubic centimeters per 2nd after you transform this number i beg your pardon is in cubic meter per 2nd by multiplying by 100 centimeters because that every meter three times to acquire into systems of cubic centimeters per second. Part C, the circulation will reverse once the pressure because of the elevation of the column of the saline solution equals the blood pressure. Therefore we have actually rho g h because that reversal, subscript r to typical the elevation at which allude the flow can reverse, equates to blood pressure and also we resolve for h r by splitting both political parties by rho g. So the height for reversal of the IV will be 1066.4 pascals, divided by 1025 kilograms every cubic meter time 9.81 newtons per kilogram i beg your pardon is 0.106 meter which is 10.6 centimeters. Therefore that way if a patient to be to was standing up and the IV bag was much less than 10.6 centimeters over their arm, then the IV drip wouldn't get in their eight anymore. So this is the write-up it's usually on, part wheels here, and also here's the bag through the saline equipment in it and the hose linked to the needle in their arm. If this distance below is ever before less 보다 10.6 centimeters, prefer if castle lift your arm approximately their head say, then the IV drip won't job-related anymore.">
