Specifications: The total length of pipe in the three inch branch is 10 ft, and the length of pipe in the one inch branch is 8 ft. Brine (sg=1.04, m=10-3Pa*s) flows at 250gpm through the entrance at point A. Assume fully turbulent flow in both branches (f=ft). Pipes are standard Schedule 40 steel pipes. Assume the globe valve is partially shut so its equivalent L/D is 1000. For Part 1 of this project, you are tasked with determining the following: The flow rate in both branches The pressure drop in both branches The overall resistance coefficient
