A patient is to receive an intravenous injection of medication. In order to work properly, the pressure of fluid containing the medication must be 109 kPa at the injection point. (a) If the fluid has a density of 1020 kg/m^3, find the height at which the bag of fluid must be suspended above the patient. Assume that the pressure inside the bag is 1 atmosphere. (b) If a less-dense fluid is used instead, must the height of the suspension be increased or decreased? Explain.
The solution includes a calculation for the required height for a bad of IV fluid given the pressure needed at injection point. Step-by-step calculations and explanations are given.
