From this paper
The density changes in a longitudinal pipe of length L, and its area A, due to temperature variation and other reasons, can be approximated as: ρ(x,t) ρ0 = ( 1 − x L )2 cos t t0 Express the mass flow in and/or out, and the mass in the conduit as function of time. Write the expression for the mass change in the pipe.
