પાવર \( = \,\,\frac{{{\text{dW}}}}{{{\text{dt}}}}\,\, = \,\,\frac{{PdV}}{{dt}}\,\, = \,\,P\frac{{dV}}{{dt}}\)

અહી , \({\text{P}}\,\, = \,\,{\text{hdg}}\,\, = \,\,{\text{10}}\,\, \times \,{\text{ 13}}{\text{.6}}\,\, \times \,\,{\text{980}}\,\, = \,\,{\text{1}}{\text{.3328}}\,\, \times \,\,{\text{1}}{{\text{0}}^{\text{5}}}\,dyne/c{m^2}\)

અને \(\frac{{{\text{dV}}}}{{{\text{dt}}}}\,\, = \) (ધબકારાની આવૃતિ )  \(×\) ( ધબકારા દીઠ રુધિર નું ડિસ્ચાર્જ ) \( = \,\,\left( {\frac{{{\text{72}}}}{{{\text{60}}}}} \right)\,\, \times \,75\,\, = \,\,90\,\,cc/s\)

તેથી, હૃદયનો પાવર વોટમાં, \(= 1.3328 × 10^5 × 90 erg/s = 1.19 × 10^7 erg/s = 1.19W\)
