SUMMARY
The power of a human heart pumping blood can be calculated using the formula for work done against pressure. Given that the heart pumps 4 liters of blood per minute at a pressure of 130 mmHg and the density of blood is 13.6 gm/cc, the power can be derived from the work done per second. The work done is calculated using the relationship between pressure, volume, and the definition of work, leading to a definitive calculation of the heart's power output.
