Question 7 of 18 You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m³, fills the lower portion of the container to a depth of 0.200 m. The fluid that is floating on top of the water is 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, pi, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 x 10° Pa. Pi = kg/m3

Water flows with a constant speed through a pipe of constant cross-sectional area in the ground floor (y1=0m) of a house. The pipe rises (y2=5.0m) to reach a shower head on the second floor. The pressure at ground level is 140kPa. a) what is the pressure at the shower head? b) what is the maximum height that water from the ground level could reach?
While taking a shower, you notice that the shower head is made up of 44 small round openings, each with a radius of 2.00 mm. You also determine that it takes 5.00 s for the shower to completely fill a 1.00-liter container you hold in the water stream. The water for the shower is pumped by a pump that is 5.50 m below the level of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g = 10 m/s2, and assume that 1 atmosphere is 1.0 105 Pa. (a) At what speed does the water emerge from the shower head? (b) What is the speed of the water in the pipe connected to the pump? (c) What is the cross-sectional area of the pipe connected to the pump?
