In each heart beat, a heart pumps 80 ml blood at an average pressure of 100 ml of Hg. What will be the power output of the herat? (Assume 60 heart beat per minute

Options

A. 1 W
B. `2.75 W`
C. `1.06 W`
D. `0.5 W`

Explanation

To find the power output of the heart, we will follow these steps:

### Step 1: Calculate the total volume of blood pumped in one minute.
The heart pumps 80 mL of blood per beat, and there are 60 beats per minute.

\[ \text{Total volume (dV)} = \text{Volume per beat} \times \text{Number of beats per minute} = 80 \, \text{mL} \times 60 \, \text{beats/min} = 4800 \, \text{mL} \]
