Question:
In the context of applied fluid mechanics, explain the difference between laminar and
turbulent flow. At what Reynolds number is the transition typically observed in a
circular pipe?
(Note: The answer to the second part of the question is typically around Re-2300
However, the exact transition point can vary depending on various factors)
Estimate the speed and Reynolds number of the sperm shown. Is this microorganism swimming under creeping flow conditions? Assume it is swimming in room-temperature water.
Topic: Heat transfer
Completely solve and box the final answer.
A 20degC water flows to 50cmx60cm flat plate with velocity of 6m/s . The flat plate surface temperature is maintained at 40deg C. The air flows parallel to the 50cm side of the plate. If the kinematic viscosity of water is 78x10-8 m2/s, at what length the flow become turbulent? If the average laminar heat transfer coefficient of water is 7740W/m2 degC, what is the overall heat transfer at the laminar section?
