The heart takes to circulate of blood.
Explanation:
The average rate of blood pumping by adult heart at rate of beats per minute is .
Our aim is to obtain the time required by heart to circulate of blood.
The rate can be referred as the adult heart pumps milliliters of blood in one second at the rate of beats per minute.
Consider be the time required for heart to pump blood.
Since, in one second the heart pumps and this can be written as,
In second the heart will pump of blood and this can be written as,
The value of is calculated as shown below.
Therefore, it takes heart to circulate of blood in approximately .
Since, blood can flow so it is called as fluids. Fluid has no fixed shape and having definite volume.
The expression for density for any fluid can be written as,
Here, is density, is the mass of the fluid and is the volume of fluid.
Thus, the heart takes to circulate of blood.
