... η is η mech Abbaspour et al. ( 9 10 12 ) developed the basic equations for one-dimensional, unsteady, compressible flow that include the effects of wall friction and heat transfer based on considering mass flow rate instead of velocity as given below: 1 ∂ P ∂ t...

... is inadequate for our purposes. In the present work, the pipe flow is treated as nonisothermal unsteady one-dimensional compressible flow. This is accomplished by treating the compressibility factor as a function of pressure and temperature, and the friction factor as a function of Reynolds number. The solution...
