The left ventricle of a resting adult’s heart pumps blood at a flow rate of 83 cm3/s, and an average heartbeat increases the pressure in the vessels by 75.5 mm Hg, the speed of the blood from zero to 26 cm/s, and the height by 11.5 cm. Calculate the total power output of the left ventricle in W. Note that most of the power is used to increase blood pressure, and the density of blood is about 1050kg/m^3

Question

The left ventricle of a resting adult’s heart pumps blood at a flow rate of 83 cm3/s, and an average heartbeat increases the pressure in the vessels by 75.5 mm Hg, the speed of the blood from zero to 26 cm/s, and the height by 11.5 cm.

Calculate the total power output of the left ventricle in W. Note that most of the power is used to increase blood pressure, and the density of blood is about 1050kg/m^3
