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.

An airship of 100m3 in size is launched from sea level and it gradually attains height until it reaches the desired altitude. A manometer measuring the gage pressure of the inside filled Helium gas show a reading of 1.2 bar at the altitude of A meters from the ground. Manometer shows reading of 2 bar when it reaches to a height of B meters. Assume; Density of air at point A = 1.00 kg/m3 and at Point B= A = 0.80 kg/m3. You can also assume average density = 0.9 kg/m3 where required. Consider temperature inside the balloon = 10°C and negligible change in temperature during the process.
