1. Water at 60 F is flowing in an 18-inch Schedule 80 steel
pipe. Find the wave speed for the system. _water = 62.37 lbm/ft3,
(Ev)water = 3.11 × 105 psi.

2. Consider the flow of a compressible fluid in a conduit
under steady state and isothermal conditions. The flow density changes from
point a to point b that is located downstream of point a. Compare the flow
Reynolds number at these points and specify whether Rea > Reb,
Rea = Reb, or Rea <>b.
