Enter Your Domestic Water Supply Parameters:	Calculation:
Enter a number Pressure Available at Building		+	PSI
Enter a number Min. Fixture Working Pressure		-	PSI
Enter a number Static Loss - System Height (ft.)	x 0.433	-	PSI
Enter a number Additional Component Loss		-	PSI

Available Pressure For Friction Loss = PSI

Enter Your Piping Supply Information:	Calculation:
Enter a number Longest Run to Fixture (ft.)		+	FT
Enter a number Fitting Allowance (% of number above)		+	FT

Total Developed Length = FT

Friction Loss Rate Per Foot (Friction Loss / TDL) = PSI/FT

Friction Loss Rate per 100 Feet (Friction Loss / TDL * 100) = PSI/100FT
