Answer:
0 deg C = 4.81E4 pressure at 0 deg
100 deg C = 6.48E4 pressure at steam point
100 deg C - 50 deg C = (6.48 - 4.81) * 10^4 = 1.67E4 Pa
50 deg C = 50 / 100 * 1.67E4 + 4.81E4 = 5.65E4 Pa Just the halfway point between the two given pressures
Centripetal acceleration is given by:
a = v²/r
a = centripetal acceleration, v = speed of cylinder at surface, r = radius of cylinder
This equation relates the speed of the cylinder at its surface to its angular velocity:
v = rω
v = speed at surface, r = radius, ω = angular velocity
Make a substitution:
a = (rω)²/r
a = rω²
Given values:
a = 9.81m/s², r = (5.0mi)/2 = 2.5mi = 4023m
Plug in and solve for ω:
9.81 = 4023ω²
ω = 0.049rad/s

For example a Helium-4 nucleus has two protons and two neutrons. The mass of the Helium-4 nucleus is less that the masses of two free protons and two free neutrons.
