4. Consider an airplane flying at 5 Km and is cruising at 80 m/s. What is the velocity of flow at a point on the airfoil where the pressure is 4.8 x 104 N/m².

1. 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.

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

9. A liquid is flowing through a horizontal pipe whose radius is 2.18 x 10-2 m. The pipe bends straight upward through a height of 10.6 m and joins another horizontal pipe whose radius is 4.36 x 10-2 m. What is the speed of the liquid in the lower horizontal pipe if the pressure in both horizontal pipes is the same? m/s MAR 27 888 5 T G 6 B tv MacBook Air H 8 N 8 DIE A F10 zoom oup by mi 04 M vauies or the puffer Am

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 12.2 cm higher than on the side connected to the balloon.    a. Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b. Find the absolute pressure in the balloon, in units of Pa.
