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 specific gravity of oil is 0.85arrow_forwardT F The specific weight of a fluid is the product of the fluid's density and the acceleration due to gravity. Stronger surface tension leads to higher capillary rise. Absolute pressures are frequently negative. If the pressure of fluid drops below the vapor pressure of that fluid at that temperature, the fluid will cavitate. F F T F F Density can be measured in lb;/ft° in the English system of units. For a hydrostatic incompressible fluid, pressure is independent of depth. A fluid with a high bulk modulus of elasticity is more difficult to compress than one with a low bulk modulus of elasticity. Viscosity is caused, in part, by the surface tension within a fluid. A fluid can resist an applied shear stress by deforming. Pressure increases faster with depth in less dense fluids than in more dense fluids. T F F F F Farrow_forward
