Pipe Sizing Calculator
Provide the following criteria and then click calculate below.

Enter the following Project Information to create your report:

   
Enter Your Domestic Water Supply Parameters: Calculation:
  + PSI
  - PSI
x 0.433 - PSI
  - PSI
Available Pressure For Friction Loss    =    PSI

Enter Your Piping Supply Information: Calculation:
  + FT
  + 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

Enter Your System Parameters for Each Table:
A   B   C  
    Water Size Table Temperature (°F)
Max. Velocity Per Water Temp (ft./sec.)
WSFU Predominant Fixture Curve
Choose the code that your state or local AHJ has adopted.
State specific codes are only listed if the fixture unit to
gpm conversion differs from a model code.
