Reynolds number (Re) is a parameter introduced to determine whether the flow of a fluid is laminar or turbulent. It is given as Re = ñvd/ç, where ñ is the density of the fluid, v is the average speed of the fluid, d is the diameter of the tube, and ç is the viscosity coefficient of a fluid. What is the unit for Reynolds number? A)kg/m s B)kg m/s C)kg m²/s² D)Re has no units

Reynolds number is a dimensionless quantity, meaning it has no units. It is derived from physical properties (density, velocity, diameter, and viscosity) whose units cancel out when calculated.
