Z Water with the density of 1000 kg/m and dynamic viscosity of 1003-10-6 kg/ms is flowing in a narrow pipe (d = 5 mm). The average flow velocity is 0.4 m/s. () (a) Calculate the Reynolds number. (1 point) (b) Is the flow turbulent or laminar? (1 point) (c) As indicated in the figure, the velocity profile is u = Umaxsin () (1) where Umax = 2Uaverage and d = d/2. Calculate the shear stress 7. Bear in mind (or check the first exercises and lectures) that du dy T=H= Hence, you must derive equation 1 with respect to y and calculate the shear stress at the wall surface (y=0). (3 points) (d) To which direction is the shear stress? (1 point) Z Water with the density of 1000 kg/m and dynamic viscosity of 1003-10-6 kg/ms is flowing in a narrow pipe (d = 5 mm).
