Is Reynolds number occurs below the critical value?(a) True(b) FalseThis question was addressed to me by my college professor while I was bunking the class.My question is taken from Laminar Flow in chapter Incompressible Flow over Airfoils of Aerodynamics

Answer» RIGHT CHOICE is (a) True

The explanation is: The laminar flow occurs when the Reynolds NUMBER is below a CRITICAL value of APPROXIMATELY 2,040 though the transition range is typically between 1,800 and 2,100. For fluid system occurring on external surfaces, such as flow past objects suspended in the fluid.
