Solution sequence for compressible flow through a pipe

4 Solution sequence for compressible flow through a pipe 

The modeller will wish to calculate the flow in the pipe from a knowledge of the pressure and specific volume in the upstream vessel and the pressure in the downstream vessel. Thus he will need to solve the 

Steady-state compressible flow 55 following set of four simultaneous equations  

Given pi, p4, y, f, L and D, the equations are dependent only on p2, the pressure at station 2 . They are presented in the order above so as to indicate the following logical solution sequence. 

When (6.27) is satisfied, it is then possible to calculate specific volume at station 2 from equation (6.7), repeated below
