Suppose a blood vessel’s radius is decreased to 88 % of its original value by plaque deposits and the body compensates by increasing the pressure difference along the vessel to keep the flow rate constant.   a. By what factor must the pressure difference increase?

A very deep point of the Pacific Ocean is at a depth of 10,100 m below the surface. What is the gauge pressure in the water at that point? The density of seawater is 1025 kg/m3. Ignore the slight variations of g and ρ with depth. Assume g = 9.80m/s2. Assume 3 significant digits.   A. 8.88 ×107 Pa   B. 2.22 ×108 Pa   C. 1.11 ×108 Pa   D. 1.01 x108 Pa   E. 3.33 ×108 Pa   F. 5.55 ×107 Pa

3. Water moves through a constricted pipe in steady and ideal flow. At the lower point shown in figure, the pressure is 1.75 × 105 Pa and the pipe radius is 3.00 cm. At the higher point located at y = 2.50 m, the pressure is 1.20 x 105 Pa and the pipe radius is 1.50 cm. Find the speed of flow (a) in the lower section and (b) in the section. upper P2 P1 Address 99+ PrtScn Home End

4.0 mm 16. Consider the following diagram. (let air be an ideal, incompressible fluid) 2.0 cm 1200 cm'/s a. If the air is found to have a flow rate of 1200 cm3/s as it leaves the 4.00 mm diameter pipe, what is the velocity of the air in both segments of the pipe? b. If the density of air is 1.28 kg/m3 and the end of the pipe on the right opens up to the atmosphere, what is the pressure of the pipe at the 2.00 cm diameter section? C. If the fluid in the bottom of the U-tube is mercury with a density of 13,600 kg/m3 what is the difference between the surface levels of both sides of the tube, marked as h in the diagram?
