The heart of a man pump 5 litre of blood through the address per minute at a pressure of 150 mm of mercury if the density of mercury when 13.6 into 10 to the power 3 kilogram metre cube and cavitation equal to 10 metre per second square then the power of heart in what is

WORK DONE BY THE HEART=PV
WHERE,P is pressure and V is the volume of blood being pumped.
therefore,P=hpg
here,h=height of mercury=150mm
= .15m
p=density of mercury=13.6*10^3kg/m^3
g=10m/s^2
also,V=5000 i.e, 5*10^-3m^3
now, P=W/T=hpgv/t
where,t=60
therefore, putting all these values we get,P=1.7W
THEREFORE,THE POWER OF HEART IS 1.7M
