ou come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a istinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m²³, fills the lower portion of the container o a depth of 0.212 m. The fluid that is floating on top of the water is 0.335 m deep. If the absolute pressure on the bottom of the ontainer is 1.049 × 105 Pa, what is the density, P₁, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and tmospheric pressure is Po= 1.013 x 10³ Pa. P₁ = kg/m³

A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork.  When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm.  What is the pressure difference in N/m2?  The density of water is 1 gm/cm3  or 1000 kg/m3.   Use 9.8 m/s2 for the acceleration of gravity.

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.

Recall the density of water is 1000 kg/m3.  b. Find the absolute pressure in the balloon, in units of Pa.

A beaker is filled with an unknown liquid up to a depth of 10.00cm . The gauge pressure at the bottom of the beaker is measured to be 1540.00Pa . What is the density of the liquid contained in the beaker?
