Question

The human heart discharges 75m3 blood pebeat
aganist an average pressure of 10cm of Hg assuming
that the pulse freqremy is 75 per minute, the power
the heart is (Hg = 13. GgM/W
Density)​

Answer 1

ANSWER:-

Force = pressure × area

= 10 × 136 × 10^3 × area × 10^-2 × 10

Power = F . v

=10× 13.6 × 10^3 × Area × v × 10^−1

=10 × 136× 10^3 × (volume/sec) × 10 −1

= 10× 13.6 × 10^3 × ( 75 × 75 / 60 ) × 10^-6 × 10^-1

= 1.275 W
