Question

1.) A liquid of density 1390 km/m^3 flows steadily through a pipe of varying diameter and height. At Location 1 along the pipe, the flow speed is 9.31 m/s and the pipe d1 diameter is 10.3cm . At Location 2, the pipe diameter d2 is 17.5 cm . At Location 1, the pipe is triangle y= 9.31m higher than it is at Location 2. Ignoring viscosity, calculate the difference between the fluid pressure at Location 2 and the fluid pressure at Location 1.

2.) 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 x 10^3 kg/m^3, fills the lower portion of the container to a depth of 0.224 m. The fluid that is floating on top of the water is 0.349 m deep. If the absolute pressure on the bottom of the container is 1.049 x 10^5 Pa, what is the density, p1 , of the unknown fluid? The acceleration due to gravity is g=9.81 m/s^2 and atmospheric pressure is Po= 1.013 x 10^5 Pa.
