The Most General Applications of Bernoulli’s Equation (Problem 27)

The left ventricle of a resting adult’s heart pumps blood at a flow rate of $83.0{\text{cm}}^3\text{/s}$, increasing its pressure by 110 mm Hg, its speed from zero to 30.0 cm/s, and its height by 5.00 cm. (All numbers are averaged over the entire heartbeat.) Calculate the total power output of the left ventricle. Note that most of the power is used to increase blood pressure.
