I wouldn't be asking if I thought I had done it correctly. I asked the question because I assumed i messed up since the problem seems
too easy
I'm not sure eta and M are interchangeable. I'm thinking I have to first relate the density to Mass per volume. Since the volume of a cylinder is...
Homework Statement
(a) Consider a cylindrical can of gas with radius R and height H rotating about its longitudinal axis. The rotation causes the density of the gas, η, to obey the differential equation
dη(ρ)/dp = κ ω2 ρ η(ρ)
where ρ is the distance from the longitudinal axis, the constant κ...
