Learning Goal: Pressure vs Depth in a fluid --U-shaped Tube capped F₁ h₁ AUnknown fluid capped F₂ water h₂ B ca 1 As shown in the figure, water is first poured into a U-shaped tube, then some unknown fluid is added to the LEFT arm. There is no intermixing between the two liquids. Then both ends are fitted with tight caps of the same cross-sectional area = 0.018 m². Force F₁9.1 N is exerted on the Left cap, and F₂ = 6.8 N is exerted on the right cap. When static equillibrium is established, in the Left arm h₁ = 0.40 m. In the right arm h₂ = 0.24 m. The density of water is p = 1000.0 kg/m³. The magnitude of the gravitational acceleration is g = 9.80 m/s² Part A - What is the pressure at point A (right below the Left cap), PA? ▶ Keep 1 digit after the decimal point, in Pascals. below the LEFT cap Submit PA = 505.6 Pa Previous Answers ✓ Correct Compare your results of PB and PA, are they indeed equal? Part B - What is the pressure at point B (right below the Right cap), PÅ ? Keep 1 digit after the decimal point, in Pascals. PB below the RIGHT cap 377.8 Pa Submit Previous Answers ✓ Correct Compare your results of PB and PA, are they indeed equal? You will find the density of the UNKNOWN fluid. Part C - What is the density of the UNKNOWN Fluid?

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.
