A steel pipe with total length 2L, where L=930m long (figure below) placed on a uniform slope has a 0.50-m diameter and a 5-cm wall thickness. The pipe carries water from a reservoir and discharges it into the air at an elevation(Z), where Z= 80m below the reservoir free surface. A valve installed at the downstream end of the pipe (point 2) allows a flow rate of 0.80 m³/s. If the valve is completely closed in 1.4, neglect minor losses, given that the roughness of steel pipe is 0.046-mm and kinematic viscosity is 1.14x 10-6

On a circular conduit there are different diameters: diameter D1 = 2 m, changes into D2 = 3 m. The velocity in the entrance profile was measured: v1 = 3 m/s. Calculate the discharge and mean velocity at the outlet profile (see figure below). Determine also type of flow in both conduit profiles (whether the flow is laminar or turbulent) – temperature of water T = 12° C. (use Reynold’s number Re), For laminar flow: Re<2320, For turbulent flow Re>2320, Kinematic viscosity of water of 12°C, v is equal to 1,24 10^-6 m2/s.
