If the speed of ultrasound in human tissues and blood is 1500m/s and the frequency of the ultrasound transmitted by the probe is 7MHz, it was noted in this case that the change in Doppler frequency is 4KHz when the angle is 600 between the direction of blood flow and the direction of ultrasound propagation. Calculate the speed of the blood flow.
