ePF Loop programmulti-purpose easy Pipe Friction with series pipe

Application example: Water Pumping Mainline

System design: To pump water from Point A  to Point B

Pump flow rate: 240 l/s total

Nominal discharge pressure required at discharge outlet: 0.2 bars

Elevation difference = 20 m

Pipe material: Ductile iron


600mm mainline pipe:

- total length = 600m

- 6 nos 90o standard elbow

- 9 nos 45o standard elbow

- 2 nos Tee

- 1 no magnetic flow meter


400mm pump suction/discharge line pipe:

- total length = 10m

- 2 gate valve

- 1 check valve

- 2 reducer/expander

- 1 no 90o elbow




Applied Working: Refer to the system schematic sketch below, calculate the total pump head required for the system. 




In ePF Loop program, the total pressure drop for the system is adding all components causing resistance to flow. You're in control the whole calculation experience.
