Answer to Question #102105 in Physics for Daniel Anthony

Question

The human heart forces 80cm3 of blood per second through the artery under a pressure of 12.5cmhg. calculate the power of the heart in wath if the density of the Mercury is 13,600kgm3

Answer 1

Volume of the blood pumping speed =80$cm^3$ /sec

Pressure = 12.5 cm hg

Density of mercury =13600 $kg/m^3$

Power=$=\dfrac{P\times V}{t}=\dfrac{12.5\times 13600\times 10^{-2}\times 9.8\times80\times 10^{-6}}{1}$

$=133280000\times10^{-8}=1.3328 J/sec$
