An open tank contains water up to a depth of 1.2m from the bottom and above it mercury for a depth of 0.7m and above it an oil of specific gravity 0.8 for a depth of 1.1m. Assume the atmospheric pressure is 1 bar. Find the gauge pressure and absolute pressure i) at the bottom of the container, ii) at the interface of water and mercury and iii) at the interface of an oil and mercury.
The Louisiana Superdome has an interior volume of 125 million ft3, covered by a 440,000 ft² roof. On a particular day, the interior air pressure gave a manometer reading of 19 inches mercury (pHg = 13.6 g/cm³). Local atmospheric pressure is 102 kPa. 1. kg Calculate the mass of the air inside, assuming an average temperature of 20 °C. 2. kN Calculate the net force applied to the roof by the interior/exterior air (do not account for the weight of the roof). Assume the roof is flat.
A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC. Assume that no gas escapes from the balloon during the flight. What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.
A quarter gallon of oil weighs about 1.85 lb. Calculate its unit weight in pcf. and specific gravity. (7.48 gal = 1 ft^3). Separate your answers with a coma
Situation 4. Glycerine having a volume of 0.452m³ weighs 5,587 Newtons. a. What is the unit weight of glycerine in KN/m³? b. What is the density of glycerine in kg/m³? c. What is the specific gravity of glycerine?
Properties of Fluids
At what depth below the surface of the oil, relative density 0.89 will produce a pressure of 130 kN/m2. What depth of water is this equivalent to? 1:Depth of oil in meters? 2:Depth of water is this equivalent to ?
solution has a specific gravity of .871. If there is 2 kg of substance/kh H2O at 10 degree C, Solve the density of substance at 10 degree C. (note: density of water at this temp is 880 kg/m^3)
A piece weighing 3 kg in air was found to weigh 2.5 kg when submerged in water. Its specific gravity is
