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

Ex ....... HYDRAUE • The pump is to be connected to a rising main which has a diameter (D) of 400 mm and a length of 137 m.The entry exit and minor head losses in the pipeline can be taken as 80D in this particular situation. The friction loss can be approximated by h; = ALQ² / 1 2D5 with A=0.04. The static lift is 10 m. By considering a single pump (P). And two of the pumps in series (P+P) and parallel (P//P) determine: > the H-Q curve of the two pump combinations » Which combination will be capable of discharging at least 0.3 m³/s, with the ability to pump up to 0.35 m³/s if the need arises. %3D
The diagram shown illustrates the flow in a circular metal duct 20 feet long. The duct has a sudden contraction at the inlet and sudden expansion at the outlet. The diameter of the duct is 10 inches and the flow rate is 600 cfm. The duct is such that both ends have area ratio of 0.6. Thus A2/A1 = A3/A4 = 0.6. Calculate:(a) Pressure loss in the duct due to sudden contraction (in. wg.).
