2. In Example 8.1, we considered an air flow with a laminar boundary layer. Let's now consider a water flow with a turbulent boundary layer. Assume a 15-cm ID pipe takes water at 20 C from a tank and delivers at a flow rate of 0.08 m³/s. Calculate the boundary layer at 2m from the entrance of the tank. Note: Follow the approach in Example 8.1 to find vxo,taking into consideration that the definition of Vx/ Vxo for the turbulent boundary layer is given by Eq. 8.56. (10 pts)
