Two identical sealed containers (1 and 2) are connected to one another by a narrow tube with a valve. Initially, the valve is closed, container 1 is filled with a fluid, and container 2 is empty. Both containers have a ruler taped to their sides in order to measure the height of any fluid they contain. The figure below shows this setup. Container 1 Container 2 valve (initially closed) ruler 1. When the valve is opened for a time interval Ar, the level of the fluid in container 1 drops by 3 cm. Describe qualitatively how you would use this information to determine the volume flow rate through the tube. Assume that the bases of the containers each have an area A. Check your answer with an instructor before proceeding.1. Imagine that you have a viscous fluid flowing in a tube and that you can double one of the following parameters: tube length, tube diameter, pressure difference between the ends of the tube, or fluid's viscosity. Which parameter, if doubled, would cause the largest change in the volume flow rate? Explain your reasoning. 2. Based on the data you used in part C, if the hematocrit of a patient's blood were to change from 42% to 55% and at the same time the diameter of one of the patient's vessels were to decrease by 1% due to vasoconstriction, by how much (and in what direction) would the patient's blood pressure have to change in order to maintain the same volume flow rate
