Additionally, some materials, such as PEX, are flexible and can be prone to collapsing if not properly supported, which can slightly reduce the actual water pipes diameter and restrict flow over time. To maintain an optimal velocity, usually between 5 and 8 feet per second for cold water supply, the pipe diameter must be adjusted.
Choosing Pipe Diameter to Minimize Friction Loss
Smaller branches leading to sinks or toilets often use 1/2 inch tubing. This increase is necessary to meet the high simultaneous demand required to flush toilets, supply cooling towers, and service numerous fixtures without a drop in pressure.
Even if the initial pipe size seems adequate for the GPM, a long unbroken pipe run can result in insufficient pressure reaching the end of the line. When replacing pipes or integrating different materials, it is essential to use the internal diameter (ID) rather than the nominal size for calculations.
Choosing Pipe Diameter For Friction Loss
This size provides enough capacity to serve multiple bathrooms, a kitchen, and laundry facilities simultaneously. The Role of Friction Loss As water travels through a pipe, it encounters friction against the inner walls, which causes a drop in pressure known as friction loss.
