1. Given an air with a known temperature and pressure of 4 degree Celsius and 105 KPa, respectively, find the density of the air.
2. A rigid container is closed at one end and measures 7 inches diameter by 14 inches long. The container is held vertically and is slowly moved downward until the pressure in the container is 16.5 psia. What will be the depth of the water surface measure from the free water surface?
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.
The pressure in a fluid at rest decreases with depth.
