1/ water is flowing smoothly in a closed pipe system. At one point the speed of the water is 3.0m/s, while at another point 2m higher the speed is 5.0m/s. (a) if the pressure is 50kPa at the lower point, what is the pressure at the higher point? (b) What would the pressure at the upper point be if the water were to stop flowing and the pressure at the lower point were 40kPa? (c) Determine the volumetric flowrate and the cross sectional area of the tube at the higher point if the cross sectional area at the lower point is 30cm squared.

2/ a small glass plate of 250cm squared is sliding on a horizontal flat surface covered by water layer of 3mm thick. find the force required to move the plate at a constant velocity of 0.1m/s. the viscosity of the water is 10 to the minus 3 Pas.

3/ the blood flow through a large artery in a dog is diverted through a venturi flow meter. the wider part of the flow meter has an area A1=0.08cm squared, which equals the cross sectional area of the artery. the narrower part of the flow meter is 25Pa. What is the velocity v1 of the blood in the artery? (the density of the blood is 1080kg/m cubed.

Solution Summary

Three very good problems related to ideal and viscous flow of fluids are solved.

For laminar flow in the entrance of to a pipe, as shown in figure, the entrance is uniform u=U0, and the flow downstream is parabolic in profileu(r)=C(r0^2-r^2). Using integrla relations, show that the viscous drag exerted on the pipe walls between 0 and x is...

A viscousfluid is moving through a flow pipe. The flow is 2x10 to the -3 m3/s. Now, consider another tube with a fluid twice the viscosity which is moving in a pipe whose length is 3 times the original with a radius 1.5 times the original. The pressure difference across this new pipe is 1/3 that of the original. What is the f

In an industrial cooling process, water is circulated through a system. If the water is pumped with a speed of 0.45 m/s under a pressure of 400 torr from the first floor through a 6.0-cm diameter pipe, what will be the pressure on the next floor 4.0 m above in a pipe with a diameter of 2.0 cm?

4. Show that the speed of the fluid at points on the cylindrical surface in Example 2, Sec. 108. (below) is 2A| sin θ| and also that the fluid pressure on the cylinder is greatest at the points z = ±1 and least at the points z = ± i

The pipe U-band in the figure attached is connected to a flow system by flexible hoses that transmit no force. The pupse has inner diameter of 3 inches. Water is flowing through the pipe at a rate of 600 gallons/minute. The pressure at point 1 is 5 psig and at point 2 is 3 psig

Q: A meter long hose of 14cm diameter is connected to a second hose which is 4 meters long and 7cm in diameter. At the open end of the second hose water flows out at a rate of 8 cm^3/sec. What is the ratio of the speed of the water flowing in the second hose to the speed of the water flowing in the first hose?
