Which of the following must be the same for an incompressible fluid at a junction where several pipes meet under steady-state conditions?
(a) The gauge pressure is identical in every pipe connected to the junction.
(b) The total mass flow rate entering the junction equals the total mass flow rate leaving it.
(c) The dynamic pressure 21ρv2 is the same in every pipe connected to the junction.
(d) The average speed of the fluid is identical in all of the pipes.
