Question:
(A) A large balloon used to sample the upper atmosphere is filled with 565 m3 of helium. What is the mass of the helium (in kg)?
(B) Find the gauge pressure (in psi) at the bottom of a freshwater swimming pool that is 19.2 ft deep.
(C) An ebony log with volume 15.8 ft3 is submerged in water. What is the buoyant force on it (in lb)? (Enter the magnitude.)
(D) An empty storage tank has a volume of 1,210 ft3. What is the buoyant force exerted on it by the air? (Assume the air is at 0C and 1 atm.)
(E) A modern-day zeppelin holds 7,070 m3 of helium. Compute its maximum payload at sea level. (Assume the helium and air to be at 0C and 1 atm.)
