- Chapter 12 Fluid Mechanics A level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m3 that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m2. What is the speed of the flow at this second position?At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer hereA horizontal segment of pipe tapers from a cross-sectional area of 44.6 cm2 to 0.500 cm2. The pressure at the larger end of the pipe is 1.30 × 105 Pa, and the speed is 0.0400 m/s. What is the pressure at the narrow end of the segment? ___Pa
- X A 1m tall cylinder is filled with half water and half oil. What is the total pressure (in Pa) at the base of the cylinder? Density of water is 1000 kg/m^3 and density of oil is 900 kg/m^3. * 40,000 5,000 9,000 9,500 Correct answerA liquid is flowing through a horizontal pipe whose radius is 0.0301 m. The pipe bends straight upward through a height of 8.80 m and joins another horizontal pipe whose radius is 0.0726 m. What volume flow rate will keep the pressures in the two horizontal pipes the same? Number Units 202A vacuum-style lift assist exerts a vertical force on an object by attachment of one or more suction cups to the top of that object. For a lift with four suction cups to provide at least 500 N of lifting force, what is the minimum vacuum pressure (mm Hg) allowable inside each 76-mm-diameter cup attached to the object? Pcup i mm Hg
- Water travels through a pipe at 9.11 m/s. The pipe contracts from a crossectional area of 1.9 m2 to an area of 0.211 m2. a) What is the speed of the water in the second part of the pipe in m/s? m/s b) How much is the pressure change in KPa as the pipe contracts? The density of water is 1000 kg/m3. Enter a positive value for an increase in pressure, a negative value for a decrease. kPa1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question. Comment > Thank yo!!A typical blood pressure is 120 mm Hg. How high above the injection site would you need to hang an IV bag so that the fluid enters the blood stream at this pressure? Assume the IV fluid has a density of 1000 kg/m3. Remember, 1 mm Hg = 133 Pa
