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 \(13.6 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3} \text { and } \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}\) then the power of heart in watt is:
- 1.50
- 1.70
- 2.35
- 3.0
Answer
(B) 1.70
