Problem 7. (The speed of blood) The aorta (the main blood vessel coming out of the heart) has a radius of about 1.0 cm and the total cross section of the major arteries is about 20 cm². The density of blood is 1.05 g/cm3. A. Given that the velocity of blood pumping through the aorta is about 48 cm/s, what is the total current of the blood passing through the aorta (in grams of blood per second)? B. If all...

What is the average blood velocity in the major arteries if the total cross-sectional area of the major arteries is 20 cm2? b. What is the total flow rate? c. If the blood in the circulatory system goes through the capillaries, what is the total cross-sectional...
Water at 15 degree Celsius , density = 999kg/cubic meter, viscosity = 0.001138 kg/ms , is flowing steadily in a 5 cm diameter horizontal pipe made of stainless steel at a rate of 0.006 m3/s . Determine the pressure drop, the head loss and the required pumping power input for flow over a 60m long section of the pipe.
A river is flowing at a flow rate of 12 cubic meters per second with a background BOD of 2 milligrams per liter of Dissolved Oxygen. A large waste spill with a five day BOD of 230 mg/L is discharged into the river at a flow rate of 2 cubic meters per second. Assuming instantaneous mixing immediately at the point of discharge, find the ultimate BOD of the river water after mixing with the waste.

Assuming that water has a density of exactly 1.00 g/cm3, find the mass of one cubic meter of water in kilograms. Suppose that it takes takes 8.0 h to drain a container of 7430 m3 of water. What is the "mass flow rate", in kilograms per second, of water from the container?
Determine whether the kinetic-energy term is significant for measurement of pressure in the human descending aorta. Assume that the peak velocity of flow in the center of the aorta is approximately 1.5 m/s and that the density of the blood p is 1060 kg/m 1) (In general, if the true value is N and the error is n, then if n/N > 5%, the error is significant if n/N < 1%, the error is not significant, if 1% < nN...
