Question

If blood flow through heart is 5 meter/minute and pressure is 150 mm of hg then how much force exerted by the blood

Answer 1

Explanation:

pressure= hdg

here h= height of mercury

d= density= 13.6x 10^3kg/m3

g= 10m/s

now, pressure= 150 x 10^-3 x 13.6 x 10^3 x 10

= 2

here, v= 5000 and t= 60sec

now, power= hdgv/t

= 2 x 5000/60

= 1.7J
