**PipeFlow**

This calculator computes the properties of a liquid or a gas passing through a straight length of pipe.

Refer to the technical help page for the downloadable version of this calculator for additional assistance.

You may use any units you like, but remember; you only get out what you enter.

We provide typical metric and Imperial units that you may (or may not) wish to use, but the output units provided are only valid if the input units (as displayed) are applied

This data applies to either (and both) of the calculation options below; Liquid and Gas.

This data applies only to calculations for [incompressible] liquid flow in a pipe.

This data applies only to calculations for [compressible] gas flow in a pipe.

This **PipeFlow** calculator is accessible from anywhere in the website using the shortcut key; "Alt" + "p".

The "**Reset**" button clears all calculations on the page and reinstalls default values (this button may not respond in the FireFox browser).

Reset can also be achieved by pressing the "F5" key.

In this calculator, it is assumed that the density of the liquid does not vary with pressure.

The pressure drop (δp) is due entirely to the friction from surface roughness (ϵ).
