Hydrant Ring Main System: Hydraulic (Pressure Drop) Calculation  

-  comparison example with ePF Loop program (Windows)

total pressure drop calculation in series (branch) pipe + loop ring main pipe network

Comparison example: Hydrant ring main system

This example compares the results obtained by ePF Loop program vs a 3rd party program.

 

System design: 2 hydrants to operate at any one time; FH3 at 38 l/s, FH4 at 19 l/s.

Minimum operating pressure at hydrant: 3 bars

Hydrant pipe diameter and material coefficient: see results print-out below.

Change in elevation height = 2.6m (pressure gain); hydrant pumps and tank located at 2nd storey.

For ease of comparison, this example excludes equivalent length of valves and fittings.
