At a given instant, the blood pressure in the heart is 1.50 104 Pa. If an artery in the brain is 0.40 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. (See Table 11.1 for appropriate constants.)

Answer #1

P1 = 1.50*10^4 Pa

P2 = ?

h2 - h1 = 0.40 m

Density of blood ρ = 1060 Kg/m^3

According to bernoullis pricniple

            P2 = P1 + ρg(h1 - h2)

                 = 1.50*10^4 + [1060*9.8*(-0.4)]

                 = 1.5*10^4 - 0.415*10^4

                 = 1.085*10^4 Pa

    The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...

    Read the following scenario Blood flowing away from the heart is under tremendous pressure, able to travel to just about any portion of the body. however, blood pressure drops considerably as it moves away from the heart. When blood finally reaches capillaries, the blood pressure drops to nearly zero. Therefore, when a person is standing, blood returning from the feet is not moved back towards the heart by heart contractions. Because of the changes in blood pressure through the circulatory...
