An open-tube mercury manometer is used to measure the pressure in an oxygen tank. The atmospheric pressure is 1020 mbarmbar . 1 barbar = 105105 N/m2N/m2. The density of mercury is 13.6×103kg/m313.6×103kg/m3. part a) Determine the absolute pressure (in PaPa) in the tank if the height of the mercury in the open tube is 21.5 cmcm higher than the mercury in the tube connected to the tank. part b)Determine the absolute pressure (in PaPa) in the tank if the height of the mercury in the open tube is 8.6 cmcm lower than the mercury in the tube connected to the tank.

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.

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 22.3 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.

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. Comment > Thank yo!!

QUESTION 8 In a lab, a foot-long test tube contains gasoline (density equal to 748.9 kg/m³) and oil (density equal to 950 kg/m³). The gasoline occupies the upper half of the tube while the oil occupies the lower half of the test tube. Compute for the pressure at the middle of the tube (at the interface between oil and gasoline). 1950.2 N/m² O 1118.5 N/m² 890.4 N/m² O 2537.3 N/m² O None of the choices given

Consider an open cylindrical tank that is half-filled with water and half-filled with oil as shown below. The pressure above the open lid of the tank is Patm. The density of water and oil are ρω and ρoil respectively. What is the pressure at the interface between the oil and water? a. P_atm + (rho_w)gh b. (rho_w)gh c. (rho_oil)gh d. P_atm + (rho_oil)gh

A 60-kg person's two feet cover an area of A=146 cm2. Assume the person is at rest. If the person stands on one foot, what is the pressure under that foot (Pa)?. Consider g 10 m/s?. A. 328767 B. 493151 C. None D. 164384 E. 82192

A Moving to another question will save this response. Quèstion 1 An open-tube manometer is used to measure the pressure in an oxygen tank. when the atmospherric pressure is 1,025 mbar. What is the absolute pressure (in Pa) in the tank if the height of the mercury in the open tube is 4.1 cm lower. (1bar = 1 x 105Pa Density of mercury is 13.6 x 10³kg/m3.) A Moving to another question will save this response.
