The flow is streamlined. This is because the Reynolds number (Re) for this flow is less than 2000, which is the critical value for the transition from laminar to turbulent flow. The Reynolds number can be calculated as Re = (ρvD)/μ, where ρ is the density of water, v is the flow velocity, D is the diameter of the pipe (2 cm), and μ is the viscosity of water. Plugging in the values gives Re = 90, which is well below the critical value of 2000, indicating a streamlined flow.
