2. a. If there are two points A and B. A is located at a distance of h = 5.50 m below you and B is located at a distance h=5.50 m above you. Calculate the pressure difference at each of these two points to the pressure at your position. b. A garden hose has an unobstructed opening with a cross sectional area of 2.85x104m². It fills a bucket with a volume of 8.00x10-³m³ in 30 seconds. Find the speed of the water that leaves the hose through (i) the unobstructed opening and (ii) an obstructed opening with half as much area. c. The water tank is open to the atmosphere at the top and bottom opening pipe. Find the speed of the liquid leaving the pipe at the bottom if h=25 cm. What principle you use in here? d. Fluid is flowing from left to right through the pipe shown in the drawing.Points A and B are at the same height, but the cross-sectional areas of the pipe are different at the two locations. Points B and C are at two different heights, but the cross-sectional areas of the pipe are the same at these two locations. Rank the velocities at three locations from lowest to highest? Rank the pressures at the three locations from lowest to highest? Aº A h Bo e. A container has a vertical tube, connected to it at its side, as shown in the figure. An unknown liquid reaches level A in the container and level B in the tube. Level A being 5.0 cm higher than level B. The liquid supports a 20-cm high column of oil, between levels B and C, whose density is 900 kg/m³. Calculate the density of the unknown liquid. B 20 cm 15.0 cm
