This calculator is used to calculate pipe friction losses for straight piping handling water and water with varying percentages of ethylene glycol. The calculator uses an algorithm developed from the basic principles of fluid mechanics. The program is based on the Darcy-Weisbach equation, the Colebrook equation, and the Moody equation. The program is intended for use only on straight piping. The program does not include pressure losses due to elevation differences, or flow through fittings.
