I would like help to calculate peak blood flow rate in aorta when given radius and peak blood velocity?
Bernoulli Equation: For peak pressure, you only need peak velocity. Peak pressure is 4 x the square of the peak velocity. If the peak velocity is 4 m/s, the peak pressure is 64 mmHg. The peak velocity IS the peak flow rate. For example, if peak velocity is 5 l/min, then the peak flow rate is 5 l/min. Is that what you meant? ...Read more
