Question

what is the minimum pressure required to the force from the heart to the top of the head distance =50 CM Assume the density of blood to be 1.06 gmcm^-3
​

Answer 1

Answer:

Here, H2−h1=40cm,

ρ=1.04gcm−3

Ac cording to Bernoulli's Theorem

P1+ρgh1+12ρυ21=P2+ρgh2+12ρυ22

or P1−P2=ρg(h2−h1)+12ρ(υ22−υ21)

Let υ2=υ1 then, P1−P2=ρg(h2−h1)

=1.04×980×(40)=4.1×104dyne/cm2.
