PROBLEM 1. In a hydraulically smooth pipe flow, wall shear stress (to) is measured as 1.5 N/m2. Pipe diameter is 0.2 m. a) Please draw velocity profile in the pipe (for the half of the pipe) by using a 0.0001m interval of the distance from the pipe wall (y) (i.e. y = 0, 0.0001, 0.0002, ...). You need to use Microsoft Excel for doing this calculation considering the high number of calculation points. (The fluid is water with a kinematic viscosity (v) of 10-6m/s and density of 1000 kg/m2.)

Consider a rectangular channel with an aspect ratio greater than 5 (width B and depth zo). The velocity distribution in the central plane of the channel is approximated as u = k1(z) 1/2. Here u is the streamwise velocity and is a function of the bed-normal direction z and k1 is a constant. Assuming the velocity distribution is similar across the width, calculate the average velocity for the cross-section, the energy and momentum coefficients.
