The heart of a man pumps $\displaystyle 5$ litres of blood through the arteries per minute at a pressure of $\displaystyle 150$ mm of mercury. If the density of mercury be $\displaystyle 13.6 \times 10^3 \mathrm{~kg} / \mathrm{m}^3$ and $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ then the power of heart in watt is :
