### Pressure Loss in Straight Gas Lines Calculator at GlobalSpec

The Pressure Loss in Straight Gas Lines Calculator is used to determine the pressure loss from friction in straight pipes or tubes that transport gases. This calculator is useful for very small piping or tubing, and can handle flow through small channels. It includes inlet and outlet losses, but cannot accommodate losses due to fitting and valves.

### PEX tubing technical specifiions and general

(8 x OD). For 1/2" PEX with OD of 5/8", minimum bending radius is 8 x 5/8" = 5". Over-bending the PEX pipe, deforms its’ round shape, restricts flow and over-stresses the pipe. Note: minimum bending diameter only refers to the 90-degree and 180-degree (U-shaped) bends. Parallel runs of pipe can be spaced as close as necessary.

### Pressure drop in pipe fittings and valves | equivalent

In long pipelines most of the pressure drop is due to the friction in the straight pipe, and the pressure drop caused by the fittings and valves is termed the "minor loss". As pipes get shorter and more complied the proportion of the losses due to the fittings and valves gets larger, but by convention are still called the "minor losses".
