Pn Normal pressure (psi), where Pn = Pt - Pv
NOTES:
- Pressures are balanced to 0.01 psi. Pressures are listed to
0.1 psi. Addition may vary by 0.1 psi due to accumulation of
round off.
- Calculations conform to NFPA 13.
- Velocity Pressures are not considered in these Calculations

=======
SAFETY PRESSURE 60.5 psi
Available Pressure of 133.6 psi Exceeds Required Pressure of 73.1 psi
This is a safety margin of 60.5 psi or 45 % of Supply
Maximum Water Velocity is 24.5 fps

HYD REF Hydraulic reference. Refer to accompanying flow diagram. __
K FACTOR Flow factor for open head or path where Flow (gpm) = K x -\/P
Qa Flow added or subtracted
Qt Total flow
DIA Actual internal diameter of pipe
C Hazen Williams pipe roughness factor
Pf/ft Friction loss per foot of pipe
PIPE Length of pipe
FTNG'S Number of fittings. See table above.
TOTAL Total length (PIPE + FTNG'S)
Pt Total pressure (psi) at fitting
Pe Pressure due to change in elevation
where Pe = 0.433 x change in elevation
Pf Friction loss (psi) to fitting
where Pf = l x 4.52 x (Q/C)^1.85 / ID^4.87
Pv Velocity pressure (psi)
where Pv = 0.001123 x Q^2/ID^4
Pn Normal pressure (psi), where Pn = Pt - Pv
NOTES:
- Pressures are balanced to 0.01 psi. Pressures are listed to
0.1 psi. Addition may vary by 0.1 psi due to accumulation of
round off.
- Calculations conform to NFPA 13.
- Velocity Pressures are not considered in these Calculations
