SUMMARY
The maximum average flow velocity for water flowing through a pipe with a diameter of 50.0 mm at 20°C, ensuring laminar flow, can be determined using the Reynolds number formula: Re = (pvd)/n. For laminar flow in a circular pipe, the Reynolds number must be less than 2000. Given the properties of water at 20°C (density p = 998 kg/m³ and dynamic viscosity n = 1.0 x 10^-3 Pa.s), users can calculate the maximum velocity by selecting an appropriate Reynolds number that guarantees laminar flow.
