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.
