The average flow velocity appears to be _______ cm/s in arteries.(a) 5 to 10(b) 10 to 12(c) 12 to 18(d) 20 to 25The question was asked during an interview.I'd like to ask this question from Application of Telemedicine topic in chapter Telemedicine Technology of Biomedical Instrumentation

Answer» CORRECT answer is (d) 20 to 25

Easy explanation: The flow-induced VOLTAGE of an electromagnetic flowmeter is, within certain LIMITATIONS, proportional to the velocity of the flow. This velocity is the average across the flow stream with an axis symmetric velocity PROFILE. The average flow velocity appears to be 20 to 25 cm/s in arteries and 10 to 12 cm/s in veins.
