Mechanical Engineering QUESTION #2400
Question 1
In the general Bernoulli energy equation, the term \(H_A\) represents:
  • Head loss due to friction
  • Energy added to the fluid by a pump (pump head)✔️
  • Energy extracted from the fluid by a turbine
  • Velocity head at section A
Correct Answer Explanation
In the extended Bernoulli equation: \(H_A\) is the head added by a pump, \(H_L\) is the head loss due to friction, and \(H_E\) is the head extracted by a turbine.
