The radius of the aorta is about 1.3 cmcm , and the blood passing through it has a speed of about 40 cm/scm/s . Calculate the average speed of blood flow in the major arteries of the body, which have a total cross-sectional area of about 1.8 cm2cm2 .

(a) Blood with a density p = 1.00 g/cm³ is flowing with a speed of 23 cm/s through an aorta with a cross-sectional area of 2.2 cm². Determine the mass flow rate (in g/s) of blood. g/s (b) If this aorta branches to a number of capillaries which have a combined cross-sectional area of 2.6 x 10³ cm², determine the flow speed (in cm/s) of the blood in the capillaries. cm/s

When physicians diagnose arterial blockages, they quote the reduction in flow rate. If the flow rate in an artery has been reduced to 14.3% of its normal value by a blood clot and the average pressure difference has increased by 23.0%, by what factor has the clot reduced the radius, ro, of the artery? r= ro

In the hydraulic system, the piston on the left hasa diameter of 5.1 cm and a mass of 2.3 kg. The piston on the right hasa diameter of 13 cm and a mass of 3.6 kg. If the density of the fluid is750 kg/m3, what is the height difference h between the two pistons?

A nozzle with a radius of 2.5 mm is attached to a garden hose with a radius of 9 mm. The flow rate through hose and nozzle is 500 cm3/s. The speed of water in the hose is

Calculate the hydrostatic difference in blood pressure between the brain and the foot in a person of height 1.03 m. The density of blood is 1060 kg/m3.

Blood speed in a normal segment of a horizontal artery is 0.1 m/s. Anabnormal segment of the artery is narrowed down by an atherosclerotic plaque to onefifth the normal cross-sectional area.a) What is the blood speed in the constricted segment of the artery? b) What is the difference in blood pressures between the normal and constricted segments of the artery? The mass density of blood is 1060 kg/m3.

When physicians diagnose arterial blockages, they quote the reduction in flow rate. If the flow rate in an artery has been reduced to 12.3% of its normal value by a blood clot and the average pressure difference has increased by 27.0%, by what factor has the clot reduced the radius, ro, of the artery?

Gold can be hammered into decorative gold leaf, which is only 1.00E-07 m thick. If 1.50 troy ounce of gold is hammered into gold leaf, what is the area that can be covered when used for decoration? 1 troy ounce = 31.1 g, and the density of gold is 19.3 g/cm3.

Calculate the hydrostatic difference in blood pressure between the brain and the foot in a person of height 1.83 m. The density of blood is 1.06x103 kg/m3
