Part A A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood What percentage of the cross-sectional area of the patient's artery is blocked by the plaque? pressure just before the region of blockage and Express your answer as a percentage finds that it is 1.20x104 Pa , while in the region of blockage it is 1.15x104 Pa . Furthermore, she knows that blood flowing through the normal artery AEQ just before the point of blockage is traveling at 29.0 ? cm/s , and the specific gravity of this patient's blood is 1.06. o is blocked Submit Request Answer Part A At a certain point in a horizontal pipeline, the water's speed is 2.50 m/s and the gauge pressure Find the gauge pressure at a second point in the line if the cross-sectional area at the second point is twice that at the first. is 1.90x104 Pa . Express your answer in pascals. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Water pressure in the home. IVO AEQ Pgauge Pa Submit Request Answer Part A Water is flowing in a cylindrical pipe of varying circular cross-sectional area, and at all points the water completely fills the pipe. At one point in the pipe, the radius is 0.145 m . What is the speed of the water at this point if the volume flow rate in the pipe is 1.15 m /s. Express your answer in meters per second. IVO AEd ? U = m/s Submit Request Answer Part B At a second point in the pipe, the water speed is 4.00 m/s . What is the radius of the pipe at this point? Express your answer in meters. AEd CE ? R = m
