The heart of man pumps 4000 c.c. of blood through the arteries per minute at a pressure of 130 mm Hg. If the density of mercury is 13.6 × 10 3 kg/m 3 , what is the power of the heart?
Text Solution
Verified by ExpertsThe correct answer is:
A
Power = Av 3 d
= (Av) (v 2 d)
= (volume per sec) × (pressure)
= 
× (130 × 10 –3 × 13.6 × 10 3 × 10)
= 1.15 watt
