5.16. Water is flowing in a 3-cm-diameter pipe at an average velocity of Uav 2 m/s. Assuming water density of ρ-1000 kg/m 3 and viscosity μ-10-3 N s'm2, calculate the velocity at the center of the pipe, the shear τ at the wall, and the Reynolds number. Assuming laminar flow, calculate friction coefficient C and pressure drop dp/dx.
06:20 marks) The water is flowing with a flowrate of Q= 0.5 m3/s in a pipe of length 1900 m, pipe diameter 600 mm and pipe thickness 16 mm. The pipe is elastic, bulk modulus of water Ep= 2.1 x10° N/m2, The modules of elasticity for the pipe material Ep = 3 x1011N/m2. At the end of the pipe, a valve is provide.
