A) 1.50
B) 1.70
C) 2.35
D) 3.0
Correct Answer: B
Solution :
Pressure = 150 mm Hg Pumping rate \[=\frac{dV}{dt}=\frac{5\times {{10}^{-3}}}{60}{{m}^{3}}/s\] Power of heart \[P.\frac{dV}{dt}=\rho gh\times \frac{dV}{dt}\] \[=(13.6\times {{10}^{3}}\,kg/{{m}^{3}})(10)\times (0.15)\times \frac{5\times {{10}^{-3}}}{60}\] \[=\frac{13.6\times 5\times 0.15}{6}=1.70\,\text{watt}\]You need to login to perform this action.
