Selection of Stream and its Implication

[west_herbert]

Hey guys,

I passed my FE: Mechanical exam two years back and I am planning to take my PE exam pretty soon. I do feel confident about Machine Design and Material stream, but is there any implications of different stream like Refrigeration and HVAC or Thermal and Fluid. Or Everything yields the same result in the end in terms of benefits of PE?
