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 glucose solution being administered with an IV has a flow rate of 2.34 cm3/min. What will the new flow rate be (in cm3/min) if the glucose is replaced by whole blood having the same density but a viscosity 2.70 times that of the glucose? All other factors remain constant.

(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

Local authorities of Ankara built a basin as cylindrical tank with an upper diameter D1 = 1500m, lower diameter D2 = 750m and height H = 25m, in Ankara as shown in the figure. Nowadays we face out drought periods, the water height in the basin is at the level of 9 m. This value should not fall below 5 m (critical point). Regional officials estimate that the consumption rate in the city is 71620 m / day from the pipe with 2 m in diameter, and the water inlet flow rate from various source (rainfall, current) to the basin will be 150000 m3/ day. The independent variable shows the time in t days, and how long does the water level in the tank (basin) reach the critical value?(ρ = 1000kg / m3)

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.

: In Niagara falls 5800 m3 of water flows every minute. What is the flow rate ( Q)?

The water flowing through a 1.9 cm (inside diameter) pipe flows out through three 1.2 cm pipes. (a) If the flow rates in the three smaller pipes are 28, 17, and 10 L/min, what is the flow rate in the 1.9 cm pipe? (b) What is the ratio of the speed of water in the 1.9 cm pipe to that in the pipe carrying 28 L/min? (a) Number Units (b) Number Units
