A hоrizоntаl centrifugаl pump mоves 60 °F wаter from an open reservoir up to a tee that splits the flow into two parallel paths. Both paths discharge to the atmosphere. The pump runs steady at 200 gpm, and all piping is 5-inch Schedule 40 commercial steel. Suction side (reservoir → pump) The pump centerline sits 10 ft above the water surface. Water enters the pipe through a sharp-edged, inward-projecting entrance, rises vertically 10 ft to a 90° standard elbow, then runs 25 ft horizontally to a fully-open globe valve, and from there directly into the pump suction. Discharge side (pump → atmosphere) After the pump, water travels 50 ft of straight horizontal pipe to a standard tee. The tee splits the flow into two paths: • RUN path: 10 ft of straight pipe, then discharge to atmosphere at the same elevation as the tee. • BRANCH path: 5 ft of vertical pipe (rising), then a 90° standard elbow, then 10 ft of horizontal pipe, then discharge to atmosphere. Important: There are two elevation changes in this system: the 10-ft suction lift (reservoir up to pump) and the 5-ft rise on the branch (tee up to branch outlet). For each pipe section, you must account for BOTH the elevation change AND the friction (pipe wall) losses and minor (fitting and valve) losses. Do not skip either contribution. The pressure drop across each path after the tee is same for both Run Through and Branch Through. You need to begin with a guess and do some iteration to reach final flow distribution. Final_P01.jpg
