Water flows through a pipe 25 mm in diameter at a velocity of 6 m/s. Determine whether the flow will be laminar or turbulent assuming that the dynamic viscosity of water is taken as 1.30 × 10−3 kg/ms and its mass density as 1000 kg/m3 . If oil of specific gravity 0.9 and dynamic viscosity 9.6 × 10−2 kg/ms is pumped through the same pipe, what type of flow will occur?

Consider a rectangular plate of width B = 1m (measured in the direction normal to the plane of this sheet) and negligible thickness, which separates two fluids of densities ρ and ρw. A mass of density ρs is supported by an inextensible rope that passes through a pulley connected to one end of the plate. Consider that ρ = 1.59ρw and ρs = 2.40ρw, where ρw = 1000 kg/m3. Determine the volume that this mass must have for the system to remain in equilibrium, as shown in the figure.
