End of run (psi)
INPUTS	PipeWiz is a simple but powerful hydraulics calculator which can provide answers to many commonly asked waterworks questions. Utilizing the Hazen-Williams equations, standardized for modern plastic and iron pipelines, you can determine residual pressures, flow rates, required pipe dimensions, velocities and other hydraulic elements. The calculator is a in an "equation solver" format which means that you can simply input the data which you know and/or require and the "unknowns" will be generated. The best way to become proficient with PipeWiz is to practice with simple, intuitive conditions and then adjust the numbers as you play "what if" games. If you discover a particularly challenging or suspicious result, please don’t hesitate to contact us directly for assistance. Of course, critical applications should always be reviewed by a qualified professional engineer. Good luck and stay dry.

RESULTS	Remaining Psi at end of run	Pressure Change over Run	GPM available over a run	ID required for flow and psi	Max distance for conditions
RESULTS	psi	psi	gpm	"	feet
	Must be greater than zero	Must be greater than zero	tells how much water you will get still with req'd end psi	what size pipe to use	Max distance and still get the desired flow and pressure.

Caveats

Pipelines are presumed flowing full (no entrapped air, etc.)
H-W pipe smoothness factor appropriate for PVC, HDPE & lined ductile pipe.
No fittings, fixtures, bends or reductions are included in the system.
HTH calc is for 50ppm initial concentration. Residual depends on field conditions.
Note: Critical applications should always be reviewed by a qualified professional engineer.

Hazen-Williams Equation as utilized: PSI = Source - ((Dist x .001 x gpm^1.85 / ID^4.8655)-Fall) x .433
