p =F vector . v vector =PAv=density g h ×(volume/sec)
= 13.6×10³×10×150×10^-3×[(5×10^-3)/60]
= 1.7 watt
= 13.6×10³×10×150×10^-3×[(5×10^-3)/60]
= 1.7 watt

how solved
heyyy....sorry for late reply...i was busy...see ,we have to calculate power of heart...so, Power= W/t ..but W=Force×displacement ....F=Pressure×Area so.. Power=pressure×volume flow rate...
Volume flow rate. =dv/dt
dv/dt= (5×10^-3)/60
and pressure=density×gh
thanks
are you physics tutor
nope :/
