4 A nonviscous blood (density 1060 kg/m3) passes through a horizontal artery. If the speed of blood changes from 4m/s to 8 m/s, as it enters a narrow region, the change in pressure Ap is A) 2120 Pa B) 4240 Pa C) 25440 Pa D) 50880 Pa
Problem 2 When the human body is accelerated vertically, blood pressure in the brain will drop. Determine the maximum vertical acceleration that a human can withstand before losing consciousness, Assume a typical systolic pressure of 16 kPa and that the base of the brain is 20 cm above the top of the heart.[consider blood density = 1035 kg/m ] Problem 2 When the human body is accelerated vertically, blood pressure in the brain will drop. Determine the maximum vertical acceleration...
1. A bathyscaphe is at a depth of 6 km in the ocean. What is the pressure on it assuming density of ocean water to be 1024 kg/mA3? At a given instant, the blood pressure in the heart is 1.6 x 10^4 Pa. If an artery in the brain is 0.45 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Density of blood is 1060 kg/mA3. 2. I 3. A...
Neglecting the pressure drop due to resistance, calculate the blood pressure, in pascals, in an artery in the brain 30 cm above the heart. The pressure at the heart is 120 mm Hg. The density of blood is 1.05 g/cm3 and the density of mercury is 13600 kg/m3. Do not type in units.
QUESTION 11 Neglecting the pressure drop due to resistance, calculate the blood pressure, in pascals, in an artery in the brain 30 cm above the heart. The pressure at the heart is 120 mm Hg. The density of blood is 1.05 g/cm2 and the density of mercury is 13600 kg/m3. Do not type in units.
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...
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.)Pa
Using reasonable estimates of height differences, calculate the blood pressure difference between each of the following and the heart (specifically, pressure at the body part minus pressure at the heart): head, hand, foot. Write the answers in Pa and in mm Hg. Assuming that the pressure at the heart is 120 mm Hg, calculate the pressure at the head, at the hand, and at the foot.
Take the density of blood to be ρ and the distance between the feet and the heart to be hH. Ignore the flow of blood. (a) Show that the difference in blood pressure between the feet and the heart is given by PF − PH = ρghH. (b) Take the density of blood to be 1.05 ✕ 103 kg/m3 and the distance between the heart and the feet to be 1.39 m. Find the difference in blood pressure between these...
