A compressed air tank is designed to contain 50 standard cubic feet of air when filled to a gauge pressure of 200 atm at an ambient temperature of 70 F. Assume this is an air tank for scuba diving, and that the approximate shape of the tank is a cylinder with circular cross section. The interior volume of the tank is v=0.253 ft^3 (a) If the interior length of the cylinder is 1 ft, what would be the inner diameter? (b) It is desired that the air tank be neutrally buoyant when empty. The density of aluminum is 2700 kg/m3. If the tank is made of aluminum, what should be the wall thickness in order for it to be neutrally buoyant?

Question
A compressed air tank is designed to contain 50 standard cubic feet of air when filled to a gauge
pressure of 200 atm at an ambient temperature of 70 F. Assume this is an air tank for scuba
diving, and that the approximate shape of the tank is a cylinder with circular cross section. The interior volume of the tank is v=0.253 ft^3
(a) If the interior length of the cylinder is 1 ft, what would be the inner diameter?
(b) It is desired that the air tank be neutrally buoyant when empty. The density of aluminum is
2700 kg/m3. If the tank is made of aluminum, what should be the wall thickness in order for
it to be neutrally buoyant?
