Flow echo
WebThe formula Q = a · v states that flow (Q) is the product of area (a) of the cylinder and the velocity (v) of the fluid (i.e blood). The volume (V) that passes a specific segment is the product of the flow (Q) and time (t): V = … WebDec 18, 2024 · Flow propagation velocity can be measured using the time-of-flight (TOF) method. This involves sending an electrical pulse of a known frequency through the pipe and measuring the time it takes for the echo to travel down the pipe and back. The time that it takes for the echo to return is then used to calculate the speed of the flow.
