Mechanical Engineering QUESTION #2411
Question 1
Power transmitted by a hydraulic fluid flow (volumetric flow rate \(Q\), specific weight \(\gamma\), total head \(H\)) is:
  • \(P = \gamma Q / H\)
  • \(P = \gamma Q H\)✔️
  • \(P = Q H / \gamma\)
  • \(P = \rho Q^2 H\)
Correct Answer Explanation
Hydraulic power: \(P=\gamma QH\) (watts in SI). For a pump: \(P_{input}=\gamma QH_A/e_{pump}\).
