Show transcribed image text The average adult heart pumps about 84. mL/s of blood at 72 beats per minute. Suppose you need to calculate how long it would take the average heart to circulate 5300. mL of blood. Set the math up. But don't do any of it. Just leave your answer as a math expression.
It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%). 1.3 W. Sadr, Farokh S. Heart Matters. A normal heart in an average sized person will pump 4 to 5 liters of blood per minute. And the average heart will beat almost 4 million times per year [sic, they probably mean 40 million -- ed.]. It is estimated that the energy required to continuously pump blood at these rates is almost 5 watts of power per hour [sic, watts of power is fine, watts of power per hour is a non sequitur -- ed.]..
