A doctor employing ultrasound of 2.5 MHz evaluates a 5800 Hz frequency shift as the ultrasound reflects from blood ejected from the heart.
i) Determine the speed of the blood in the aorta? Suppose that the speed of sound in human body is around1540 m/s
ii) Determine the difference in blood pressure among the inside of the heart and the aorta? Suppose that the patient is lying down and that there is no difference in height as the blood moves from the heart to aorta.
