Kinetic energy terms matter most in

  • A.centrifugal pumps handling liquid
  • B.nozzles and diffusers
  • C.shell and tube heat exchangers
  • D.large storage vessels

Answer: B

These are the devices designed specifically to change velocity, so the term they exist to alter cannot be dropped. In the others the velocities are low enough that the kinetic term is a rounding error on the enthalpy change.
