A physics student is tasked to determine the onset of turbulence in a liquid flowing through a circular pipe. The student is given the following variables: density of the liquid, dynamic viscosity, diameter of the pipe, and average flow velocity. Using this information, the student must calculate the Reynolds number of the flow to determine if it is laminar or turbulent. Additionally, the student must explain how the transition from laminar to turbulent flow occurs and the possible consequences of turbulent flow in the pipe.
