A hydrometer is a simple device used to measure the specific gravity of liquids. t has two connected parts - a glass bulb (weighted with lead) and a cylindrical tem (with some internal scale marks). When placed in a liquid, the hydrometer Toats upright with some part of the stem extending above the liquid surface. n the figure shown, the bulb has a volume of 20 cm³ and a total mass (including the lead) of 18 g. The cylindrical stem has a iameter of 1 cm and a total length of 20 cm; the mass of the cylindrical stem is 2 g. a. Using the depth Z, derive an expression for the TOTAL volume of the hydrometer that is immersed in the liquid. b. Draw the appropriate force balance diagram for when the hydrometer is stationary in the fluid. Be sure to identify and label all the relevant forces and in which direction they act. c. When placed in an unknown liquid, the cylindrical stem extends 13.5 cm above the liquid surface. Determine the specific gravity of this liquid. BULB

A tank holds water (density of 995.7 kg/m3) with a triangular gate located at the bottom right. The gate is an isosceles triangle with a base/width of 0.7 m and a height of 1.4 m. What force (F) applied at the gate's centroid is needed to keep the gate closed? The height from the water surface to the gate centroid is given by h = 4.9 m. Please note that the side view of the gate is shown and that the force is applied at the gate's centroid, although not accurately drawn.

Problem 7 A double inverted U-tube manometer containing oil (SG = 0.8), mercury (SG = 13.6) and water is used to measure large pressure difference between gas in pipe B and gasoline in pipe A as shown in figure. Knowing that h₁ = 60 cm, h₂ = 87 cm, h3 = 35 cm, and h4 = 24 cm, determine the presure difference between A and B. Neglect the gas density and use Ywater = 9810 N/m³ for water. -Water Oil, sg=0.8 ha +B h₂ ၁၂၉၂ M Gasoline, h₁ sg=0.75 Gas Mercury, sg= 13.6

Bathyscaphes are capable of submerging to great depths in the ocean. What is the pressure at a depth of 5 km, assuming sea water has a constant specific weight of 10.1 kN m-³? Express your answer in kilopascals. The bathyscaphe contains several ballast tanks to regulate its buoyancy. If the dry mass of the bathyscaphe is 800 kg and its volume is 15 m³, the ballast tanks must contain what volume of seawater for the bathyscaphe to begin to sink? LF

The plastic block shown below measures l.5 m x/.S m x(.7 m and has a specific gravity of 0.38. The concrete block B (density = 2400 kg/m) is suspended from the corner of the plastic block by means of a cable and the plastic block is thus floating in the lake (T = 15°C) in the orientation shown. Determine the volume of the concrete block (units of liters) noting that it does not rest on the bottom of the lake, Neglect the weight and volume of the cable in your analysis. %3D %3D 1.7 m 0.5m Water Cable B
