Application Example: Two-Loop Pipe Network Flow & Pressure Drop Analysis
Refer to the 2-loop pipe network as shown, determine the flow and pressure drop in each section of the pipes. Ignore minor losses. Indicated flowrate in l/m (litre per minute).
Given data:
Pipe 1: 600m length, 250mm diameter
Pipe 2: 600m length, 150mm diameter
Pipe 3: 200m length, 100mm diameter
Pipe 4: 600m length, 150mm diameter
Pipe 5: 600m length, 150mm diameter
Pipe 6: 200m length, 200mm diameter
Pipe 7: 200m length, 100mm diameter
Pipe material & roughness: Ductile Iron cement lined, roughness 0.03mm
Water density & viscosity: Density 1000 kg/m3, Dynamic viscosity 1.306 cP
Solutions with ePF Loop . . . flow and pressure drop (head loss) calculations
The 2-loop pipe network model in ePF Loop program is as shown. It consists of Section 1 pipes (source), Section 2 pipes, Section 3 pipes and Section 4 pipes (common).
Quick start
(1) Start input pipes sequentially in Section 1 in clockwise direction, starting from the single-input supply source point (Qin).
(2) Input pipes sequentially in Section 2 and 3 in clockwise direction accordingly.
(3) In Section 4 (common pipe), input pipes sequentially in clockwise direction as in Loop A.
(4) Enter discharge flowrate (Qo) at each pipe if there is a discharge flow. Enter zero (0) if there is no discharge.
(5) Select density and material.
(6) Right click on input textbox (Qout, D, L, K) for selections.
