Question

a human heart pumps 70cc of blood at each beat against pressure of 125mm Hg If pulse sequence if 72 per minute the power of heart is ?​

Answer 1

power can be calculated as work done/time

power = n(Pdv)/t

n/t = 72/60

dv = 70cc

dv = 70*10 raise to power negative 6 cube meter

value of p given as P = (125*10 raise to power negative 3) (13.6*10 raise to power 3) (9.8) pascal, substitute all values in power and n/t

power = 1.4 watt  

Answer 2

Answer:

Explanation:

power = n(Pdv)/t

n/t = 72/60

dv = 70cc

dv = 70*10^-6

p=1.4 w
