Problem 2: Two containers have
a substantial amount of the air evacuated out of them so that the
pressure inside is half the pressure at sea level. One container is
in Denver at an altitude of about 6,000 ft and the other is in New
Orleans (at sea level). The surface area of the container lid
is A = 0.0095 m2. The air
pressure in Denver
is PD = 81500 Pa. and in
New Orleans
is PNO = 101000 Pa. Assume
the lid is weightless.
Part (a) Write an expression for the
force FNO required to remove the
container lid in New Orleans.
Part (b) Calculate the
force FNO required to lift off the
container lid in New Orleans, in newtons.
Part (c) Calculate the
force FD required to lift off the
container lid in Denver, in newtons.
Part (d) Is more force required to
lift the lid in Denver (higher altitude, lower pressure) or New
Orleans (lower altitude, higher pressure)?
