Mechanical Engineering QUESTION #2396
Question 1
Kinematic viscosity \(\nu\) is related to absolute (dynamic) viscosity \(\mu\) and fluid density \(\rho\) by:
  • \(\nu = \mu \cdot \rho\)
  • \(\nu = \mu / \rho\)✔️
  • \(\nu = \rho / \mu\)
  • \(\nu = \mu^2 / \rho\)
Correct Answer Explanation
Kinematic viscosity: \(\nu=\mu/\rho\) (m²/s). The Reynolds number \(Re=VL/\nu=\rho VL/\mu\).
