Each day, the human heart pumps about 7500 liters of blood. As a simple approximation, assume that the work done by the heart is
erik [133]

Answer with Step-by-step explanation:

We are given

Volume of blood=V=7500 L=7500\times 0.001=7.5 m^3

1 liter=0.001 m^3

Height of person=h=1.5 m

Density of blood,\rho=1050 kg/m^3

We have to find the work done and power of person's heart.

We know that

Work done,W=mgh=\rho Vgh

Where g=9.8 m/s^2

Using the formula

W=1050\times 7.5\times 9.8\times 1.5=1.16\times 10^5 J

Time,t=1 day=24\times 60\times 60=86400 s

Power, P=\frac{W}{t}

Using the formula

P=\frac{1.16\times 10^5}{86400}=1.34 Watt
