Question
Work done by a human heart is 1.5 J. find the power of human heart.
[ Given Heart beats per minute is 72]
Solution
Work done = 1.5 J
No. of heart beats = 72
total work done by heart in 1 minute = 1.5
= 108 Joule
Time taken, t = 1min
Therefore,
Power =
That is, the power of human heart is 1.8 W.
