A spherical balloon is 50 ft in diameter and surrounded by air at 60 F and 29.92 in Hg abs. (a) if the balloon is filled with hydrogen at temp of 70 F and atmospheric pressure, what total load can it lift. (b) if it contains helium instead of hydrogen, what load can it lift (lb.) if gravitational acceleration is 31.85 ft/s²?

5. The Hoover Dam, in Arizona, encloses Lake Mead, which contains 10 trillion gallons of water. The dam is 1200 ft wide and the lake is 500 ft deep. (a) Estimate the hydrostatic force on the dam, in MN. (b) Explain how you might analyze the stress in the dam due to this hydrostatic force?
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.
P1.9 A rubber balloon when fully inflated has a spherical shape with a radius of 0.3 m. The absolute pressure inside the balloon is 103 kN m²2 and the local barometric ambient pressure is 750 mm of mercury. By considering the equilibrium of a hemispherical portion of the balloon, calculate the tension in the rubber membrane per unit circumferential length. Neglect the effect of the thickness of the balloon. [Answer: 0.44 kN

An underwater pipeline must be laid 40 meters deep. The density of sea water is 1 025 kg/m³. The pipe has a mass of 40 kg per meter and an outside diameter of 300 mm. The pipe must be anchored every 5 m to the bottom of the sea. (a) What will the vertical force be on each anchor if the 4.3 pipe is empty. (b) What external pressure must the pipe be able to withstand if it is not to be crushed. [1 592 N, 402,2 kPa]
