Question

Design a cast iron (kd=8*10‐4 ft) pressurized system (pipe diameter) that would convey water at 2 ft3/s from two elevated tanks separated 200 ft long. The difference in water surface elevation between the tanks is 20 ft and the kinematic viscosity is 1.217*10‐5 ft2/s. Along the system the entrance loss and the exit loss have a KL of 0.5 and 1, respectively. Two 90 degrees bends are present (KL=3) and a global valve (KL=10) is also installed along the system.
