Doppler uses ultrasound to measure blood flow velocities. Assume that the device emits sound at a frequency of 3.2MHz, and that the speed of sound in human tissue is 1540 m/s What is the expected pulse rate if blood flows in the arteries of the large leg at a speed of 3) cm/s away from the source of the sound
