Pipe Fittings
The calculator assumes the diameter size is the same for all pipe fittings. However, you can choose to override any of the values for pipe fittings by selecting a different diameter size for any fitting. Then, enter the quantity or amount of fittings for each that apply.

|---|---|---|---|---|
| Regular 90° elbows | -inch | 0 feet | 0 feet | |
| Long radius 90° elbows | -inch | 0 feet | 0 feet | |
| Regular 45° elbows | -inch | 0 feet | 0 feet | |
| Tee (T) Line Flow | -inch | 0 feet | 0 feet | |

Total Pump Discharge Pipe Loss
WARNING: Total Pump Discharge Pipe Loss DOES NOT include other sources of pressure that pump discharge must overcome such as vertical lift, back pressure, safety margin, or boiler operating pressure that are needed to determine pump discharge pressure. Refer to individual unit sizing programs for determining pump discharge.
