Volume of the blood pumping speed =80cm3cm^3 /sec

Pressure = 12.5 cm hg

Density of mercury =13600 kg/m3kg/m^3

Power==P×Vt=12.5×13600×10−2×9.8×80×10−61=\dfrac{P\times V}{t}=\dfrac{12.5\times 13600\times 10^{-2}\times 9.8\times80\times 10^{-6}}{1}

=133280000×10−8=1.3328J/sec=133280000\times10^{-8}=1.3328 J/sec

Dear Aliyu, 1cm = 10^{-2} m and 1cm^3 = 10^{-2*3} = 10^{-6}
