- A U-tube mercury manometer is used to measure the pressure at a pointon the wing of a wind-tunnel model. One side of the manometer isconnected to the model, and the other side is open to the atmosphere.Atmospheric pressure and the density of liquid mercury are1.01 × 105 N/m2 and 1.36 × 104 kg/m3, respectively. When thedisplacement of the two columns of mercury is 20 cm, with the highcolumn on the model side, what is the pressure on the wing?arrow_forwardOne end of a tube of unknown radius is immersed to a depth of 15 mm in water and an air bubble is blown at the end of this tube. The maximum air pressure measured is 200 Pa. The same procedure is carried out in a liquid and the maximum air pressure recorded in 150 Pa. Determine the surface tension of the liquid. Data given: Density of water = 997 kg/m3 Density of liquid = 850 kg/m3 Density of air = 1.2 kg/m3 Surface tension of water = 72 mN/marrow_forwardWhen a clean glass tube with a diameter of 2 mm is immersed in water at 20 ° C, how many mm will the capillary rise occur in the glass tube? For water at 20 ° C, surface tension is given as 0.073 N / m, density 1000 kg / m3, contact angle 0 ° C and gravitational acceleration 10 m / s2.arrow_forward
- A spherical neutrophil 16µm in diameter is resting as shown in the attached photo. The pressure difference between the inside and outside of the cell is 7.5Pa. a) Draw free body diagrams of the whole cell and one hemisphere of the cell. b) Calculate cortical tension in the cell. In a micropipette aspiration experiment, a suction pressure of 52.5 Pa was used to aspirate the neutrophil membrane. c) Draw free body diagrams of the whole cell under micropipette aspiration and the portion of the cell in the micropipette. What is the diameter of the micropipette tip used to make this hemispherical projection? Next, the micropipette aspiration was stopped, and the cell was treated with Cytochalasin D, an inhibitor of actin polymerization, causing the cortical tension to decrease by half. d) Assuming the pressures inside and outside the cell have not changed, what is the new cell radius? e) If the same micropipette was used to aspirate the cell, what would be the new suction pressure?arrow_forwardAt the surface of a freshwater spring, a manatee with a small amount of air in its lungs is neutrally buoyant. The manatee now dives to a depth of 10 m. At this greater depth, the buoyant force isA. Less than the weight force.B. The same as the weight force.C. Greater than the weight force.arrow_forwardA water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure. a. If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? b. After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? c.

- Blaise Pascal duplicated Torricelli's barometer using a red Bordeaux wine, of density 984 kg/m3, as the working liquid (figure below). A long tube is upside-down, with its closed end in the air and its open end submerged in a tank of wine. A column of wine inside the tube extends from the surface level of the wine outside the tube to nearly the top of the tube. The height of the column is labeled h. The pressure outside the tube is labeled P0, and an arrow below the P0 label points down toward the surface of the tank.
