What is the greatest average speed of blood flow at 37 °C in an artery of radius 1.50 mm if the flow is to remain laminar? Take the density of blood to be 1025 kg/m", and the viscosity to be 2.084 x 10-3 Pa-s. greatest average speed: m/s What is the corresponding flow rate? flow rate: m/s Question Credit: OpenStax College Physics
64. A glucose solution being administered with an IV has a flow rate of. What will the new flow rate be if the glucose ist.Peshaced by whole blood having the same density but a viscosity 2.50 times that of the glucose? All other factors remain constant. 65. The pressure drop along a length of artery is 100 Pa, the radius is 10 mm, and the flow is laminar. The average speed of the blood is 15 mm/s. (a) What is...
I'm not sure how to solve. Do I add the two and then
multiply by 2 to get the average? could you also explain and help
with parts a,b. Thanks
Paced 10u0 Valm 22) The density and viscosity of blood are roughly 1025 kg/m3 and 2.8 mPa s, respectively. a) What is the greatest average speed of blood flow in an artery of radius 2.00 mm if the flow is to remain laminar? b) What is the corresponding flow rate?
65. The pressure drop along a length of artery is 100 Pa, the radius is 10 mm, and the flow is laminar. The average speed of the blood is 15 mm/s. (a) What is the net force on the blood in this section of artery? (b) What is the power expended maintaining the flow? 66. A small artery has a length of and a radius of . If the pressure drop across the artery'is 1.3 kPa, what's the flow rate...
The viscosity of blood is 2.10 × 10−3 Pa⋅s. * What is the pressure difference required to make blood flow through an artery of inner radius 2.00 mm and length 0.200 m at an average speed of 5.28 cm/s? ___ Pa * Blood flows through an artery of inner radius 2.00 mm and length 0.200 m at an average speed of 5.28 cm/s. What is the ratio of the pressure difference required to make blood flow through this artery to...
A small artery has a length of 1.05 times 10^-3 m and a radius of 2.7 times 10^-5 m. A If the pressure drop across the artery is 1.4 kPa, what is the flow rate through the artery in mm^3/s? (Assume that the temperature is 37 degree C, and the viscosity of blood at that temperature is 2.084 times 10^-3 N-s/m^2).
Below are typical values for blood flow through a coronary artery. Note that viscosity of the blood is not neglected. Density of blood, ρ = 1060 kg/m3 Viscosity of blood, ν = 0.004 Pa x s Flow rate, Q = 0.8 mL/s Length of artery, L = 3.5 cm Radius of artery, r = 0.2 cm For the same pressure drop, calculate the flow rate if the radius of the artery reduces by 30% its original value due to blockage?
Previously we examined blood flow through a capillary. a) The average radius of a capillary is 3.0 um. The viscosity of blood is about o.0021 Pa*s, eaclh 7) capillary is approximately 1.0 mm long with a speed of about 1.omm/s, calculate the pressure "drop" from one end of a capillary to the other. b) The average blood pressure provided by the heart is about 100 mm Hg. A physiology textbook will tell you that the pressure has decreased to 35...
The average speed of blood in the aorta is 0.365 m/s, and the radius of the aorta is 1.00 cm. There are about 2.00 × 109 capillaries with an average radius of 6.99 μm. What is the approximate average speed of the blood flow in the capillaries?
The heart pumps blood with an average volume flow rate of 80 cm3 /s into the aorta. The radius of the aorta is 0.75cm. a) What is the cross-sectional area of the aorta (in cm 2 )? b) What is the average speed of the blood flowing through the aorta, in cm/s? c) What is this speed in m/s?
