How its solved
5 A Small blood vessel near the skin has a radius of 10-5 m and length of 1 mm. The pressure drop along the blood vessel is 2.5 Pa. The viscosity of the blood is 2.5 x 10-3 Pa.s. The volume flow rate of blood through this blood vessel is A) 4.17 x 10-4m3/s B) 1.83 x 10-15m3/s C) 3.93 x 10-15m3/s D) 6.25 x 10-"m3/s

Blood contains positive and negative ions and thus is a conductor. A blood vessel, therefore, can be viewed as an electrical wire. We can even picture the flowing blood as a series of parallel conducting slabs whose thickness is the diameter 5.12 mm of the vessel moving with speed . (See in the following figure) A) If the blood vessel is placed in a magnetic field B perpendicular to the vessel, as in the figure, show that the motional potential...

A blood vessel carries blood with a viscosity equal to 0.0035 Pa.s. If the vessel has a radius equal to 1 mm and a length equal to 5 mm, what is its resistance in PRU? solve in PRU (b) The vessel from part (a) is connected in series to a second vessel with a resistance equal to 0.250 PRU. What is the total resistance of the two vessels? solve in PRU (c) If the pressure across the two vessels is...

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...

A liquid_p = 1.45 g/cm^2) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm^2, the flow speed is 248 cm/s, and the pressure is 1.20 times 10^5 Pa. In the second section, the cross-sectional area is 4.50 cm^2. Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.) m/s Calculate the smaller section's pressure. Pa Whole blood has a surface...

2. Blood flows through a tapered vessel at 2 l/min, as shown in Figure 2. Assume the flow is inviscid and steady, density is 1 g/cm, and gravity is negligible. Points 1 and 2 are 7 cm apart and the diameter changes linearly with axial position, x. Let x = 0 at point 1. a. Determine V2. Hint: you may assume that the velocity does not vary with radial position because the change in vessel diameter is gradual. Likewise, you...

A 1.7 m wide, 4000 m long rectangular channel carries 1.6 m/s of water. The depth of the flow is 0.9 m. The channel is constructed from rough-formed concrete with a roughness coefficient of n-0.015. What is the difference in elevation between the two ends of the channel?
