The lower section of a constricted pipe has a diameter of 8 cm. The upper section of the pipe, located 0.1 m above the lower section, has a diameter of 3 cm. The pressure at the lower section is 2.1 ×× 104 Pa, while the pressure in the upper section is 1 ×× 104 Pa. Assuming water moves through the pipe in a steady flow, calculate the speed (in m s-1) of the flow in the lower section. The density of water is 1000 kg m-3.

It is a fact that blood flows more rapidly in the aorta than in the capillaries. The cross sectional area of the aorta must be ___________ the total cross sectional area of the capillaries. less than equal to greater than Consider an incompressible liquid flowing in a pipe of constant diameter. ΔP is the pressure difference between the 2 ends of the pipe. Choose the correct statement regarding the volumetric flow. It will decrease with increased ΔP, and increase with greater pipe radius. It will increase with increased ΔP, and increase with greater length of the pipe. it will decrease with greater length of the pipe, and increase with greater pipe radius. it will decrease with increased viscosity of the liquid, and decrease with greater pipe radius.
Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.

A manometer containing water with one end connected to a container of gas has a column height difference of h = 0.31 m (see figure below). If the atmospheric pressure on the right column is 1.01 ✕ 105 Pa, find the absolute pressure of the gas in the container. The density of water is 1.0 ✕ 103 kg/m3. Pa
When a person inhales, air moves down the bronchus (windpipe) at 13.8 cm/s. The average flow speed of the air doubles through a constriction in the bronchus. Assuming incompressible flow, determine the pressure drop in the constriction. Neglect the change of pressure due to change in height ?y in the wind pipe. If the pressure goes down then the pressure drop is negative. Use 1.20 kg/m33 for the density of air.
An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road. (The answer is not 0.06263 m2)
