The human heart discharges 75ml of blood at each beat against a pressure of 0.1m of Hg. Calculate the power of the heart assuming that the pulse frequency is 80 beats per minute. Given, density of mercury `=13.6xx10^(3) kg//m^(3)`

The human heart discharges 75 cm^(3) of blood per beat against an average pressure of 10 cm of Hg . Assuming that the pulse frequency is 75 per minute, the power of the heart is (density of Hg = 13.6 gm cm^(-3) )

The human heart discharges 75 cc of blood through the arteries at each heart against an average presure of 10cm of mercury. Assuming that the pulse frequency is 72 per minute , the rate of working of heart in watt is (Density of mercury = 13.6 gm//cc and g = 9.8 m//s^(2)) .

In each heart beat, a heart pumps 80 ml blood at an average pressure of 100 ml of Hg. What will be the power output of the herat? (Assume 60 heart beat per minute

76 cm of mercury column is a measure of atmospherice pressure. Express it is N//m^2 Given density of mercury is 13.6xx10^3 kg//m^3

The difference in the two molar specific heat capacities of a gas is 2 calories. Calculate the mechaical equivalent of heat assuming that the molar volume of a gas a NTP is 0.0244m^(3) . (g=9.81ms^(-2) and density of mercury =13.6xx10^(3)kgm^(-3) )

A glass tube of 1 mm bore is dipped vertically into a container of mercury, with its lower end 5 cm below the mercury surface. What must be the gauge pressure of air in the tube to a hemispherical bubble at its lower end? Given density of mercury = 13.6 xx 10^(3) kg//m^(3) , surface tension of mercury = 440 xx 10^(-3) Nm^(-1) and g = 10m//s^(2)

The average work done by a human heart while it beats once is 0.5 J. Calculate the power used by heart if it beats 74 times in a minute

Calculate the total pressure at the bottom of a lake of depth 5.1 m (atm pressure =10^(5) P), density of water =10^(3)kg//m^(3),g=10m//s^(2)

The averge work done by a human heart while it beats once is 0.5J. Calculate the power used by heart if it beats 75 times in a minute.
