#### The heart of a man pumps 5 litres of blood through the arteries per minute at a pressure of 150 mm of mercury. If the density of mercury be 13.6 x 103 kg/m3 and g = 10 m/s2 then the power of heart in watt is : Option 1) 2.35 Option 2) 3.0 Option 3) 1.50 Option 4) 1.70

As we learnt

- wherein

Pressure varies with respect to depth / height

Volume rate of flow=

Pressure=150 mm of Hg

=fgh =

=20400 N/m2

Power=

This option is incorrect

Option 3)

1.50

This option is incorrect

Option 4)
