The human heart discharges `75 cm^(3)` of blood per beat against an average pressure of `10 cm` of `Hg`. Assuming that the pulse frequency is `75` per minute, the power of the heart is (density of `Hg = 13.6 gm cm^(-3)`)

`1.25 W`

`12.5 W`

`0.125 W`

`125W`

Text Solution

Verified by Experts

The correct Answer is:
