A fully developed turbulent flow of water at 20oC (density = 998 kg/m3 and viscosity = 1.002 x 10-3 kg/m. s) has an average velocity of 3 m/s at location 1. After flowing through the stainless-steel pipe with a diameter of D = 20 cm for a distance of 40 m, it undergoes sudden contraction to a diameter of d = 10 cm at location 2. 1 Determine the velocity at location 2. 2 Determine the total head loss between locations 1 and 2.
