Question

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 $13.6 	imes 10^3$ $kg/m^3$ and g = 10 $m/s^2$ then the power of heart in watt is:

[Solution] $P = ho g h \cdot \frac{dV}{dt} = 13.6	imes10^3 	imes 10 	imes 0.15 	imes \frac{5	imes10^{-3}}{60} = 1.70$ W. Answer (2).

Q. 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 $13.6 \times 10^3$ $kg/m^3$ and g = 10 $m/s^2$ then the power of heart in watt is:
