ASPE Tables V4 4.3

Developed by the American Society of Plumbing Engineers (ASPE), the Plumbing Engineering & Design Tables App serves as a comprehensive resource for professionals engaged in plumbing system design and installation. It consolidates essential equations, pipe sizing data, and reference materials derived from significant plumbing codes and standards, including the International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and National Standard Plumbing Code.

The app's information is extracted from an extensive 2,500-page handbook, positioning it as one of the most thorough tools for plumbing system sizing available on the market. This app effectively eliminates the need to carry cumbersome textbooks or to manually input data into spreadsheets, offering essential data at the user’s fingertips.

Its interactive design tables enable users to select appropriate pipe materials and other design parameters, delivering instant sizing data in both SI and English units. This functionality allows for rapid calculations of pipe flow rates, velocities, friction loss, pressure loss, and stack flow rates.

The design tables encompass a variety of formulas and equations pertinent to plumbing system projects, such as:

• Manning’s equation
• Hazen-Williams formula
• Darcy-Weisbach formula
• Bernoulli equation
• Boyle’s law
• Joukowsky’s formula
• Colebrook formula
• Spitzglass formula
• Hunter’s curve

Users can choose from various piping materials, including:

• ABS
• Cast iron
• PVC
• CPVC
• PEX
• Polyethylene (PE)
• Stainless steel
• Copper

The app contains data relevant to multiple plumbing systems such as:

• Domestic hot and cold water distribution systems
• Natural gas and liquefied petroleum gas systems
• Venting systems
• Building drainage systems
• Storm drainage systems
• Vacuum systems

Beyond pipe sizing information, additional features include:

• Drainage fixture unit (DFU) values for major model plumbing codes
• Typical resistance coefficients for valves and fittings
• Water supply fixture units (WSFU)
• Surface roughness coefficient (C) values for various pipes
• Typical hot water temperatures for plumbing fixtures and equipment
• Demographic classifications of building occupants
• Hot water demand per fixture across different building types
• Gallons (liters) of water per hour per fixture
• Suction CFM to actual CFM conversions
• Basic vacuum pressure metrics
• Torr-to-vacuum pressure unit conversions
• IP and SI pressure conversions
• Barometric pressures correlated with altitude levels
• Flow rate reduction factors due to altitude influences
• Physical and combustion properties of common fuel gases
• Averages of natural gas and propane properties
• Estimated gas demand for standard appliances
• Specific gravities for a range of gases
• Fractional, decimal, and millimeter equivalents
• Temperature equivalencies across various measures.

The complete version of the Plumbing Engineering & Design Tables App is exclusive to ASPE members. However, many features are accessible to nonmembers, providing valuable insights into the app's capabilities. Interested parties are encouraged to explore these features before considering membership at ASPE.org to maximize their professional development opportunities.
