value. (a) Standing up right (b) Sitting (c) Lying horizontally (d) Standing onone’s head?
- In an orbiting space station, would the blood pressure in major arteries in the leg
ever be greater than the blood pressure in major arteries in the neck?
- Certain globular protein particle has a density of 1246 kgm-3. It falls through pure water n=8.0*10^-4 Nm^-2s with a terminal speed of 3.0 cm h-1. Find the radius of the particle.
- Water flows through a house, whose internal diameter is 1cm at a speed of 1ms-1. What should be the
diameter of the nozzle if the water is to emerge at 21ms-1?
- The pipe near the lower end of a large water storage tank develops a small leak and a stream of water
shoots from it. The top of water in the tank is 15m above the point of leak. (a) With what speed does the
water rush from the hole? (b) If the hole has an area of 0.060 cm2, how much water flows out in one
second?
- What is flowing smoothly through a closed pipe system. At one point the speed of water is 3.0 ms-1,
while at another point 3.0m higher, the speed is 4.0 ms-1. If the pressure is 80 kPa at the lower point, what is
pressure at the upper point?
- An airplane wing is designed so that when the speed of the air across the top of the wing is 450 ms-1,
the speed of air below the wing is 410ms-1. What is the pressure difference between the top and bottom
of the wings? (Density of air = 1.29kgm-3)
- The radius of the aorta is about 1.0cm and the blood flowing through it has a speed of about 30 cms-1.
Calculate the average speed of the blood in the capillaries using the fact that although each capillary has a
diameter of about , there are literally millions of them so that their total cross section is about 2000 cm2.
- How large must a heating duct be if air moving 3.0ms-1 along it can replenish the air in a room of 300 m3
volume every 15min? Assume the air’s density remains constant.
- An airplane design calls for a “lift” due to the net force of the moving air on the wing of about 1000Nm-2
of wing area. Assume that air flows past the wing of an aircraft with streamline flow. If the speed of flow
past the lower surface is 160ms-1, what is the required speed over the upper surface to give a “lift” of
1000Nm-2? The density of air is 1.29 Kgm-3 and assume maximum thickness of wing to be one metre.
- What gauge pressure is required in the city mains for a stream from a fire hose connected to the mains
to reach a vertical height of 15.0m?
