What are some good topics to add to a Pipeline presentation? So yes, a presentation about pipelines, like for example in the US. Have any ideas??

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
