Viewing: The Fluid Flow Calculator

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. This calculator allows the user to input the fluid type, the fluid temperature, the flow rate, the pipe size, pipe length, and pipe material. The calculator then determines the velocity, the Reynolds number, the Moody friction factor, the pipe friction factor (from the Colebrook equation), the pipe head loss, and the pipe friction loss in PSI. While this calculator is intended for use on systems handling water and water with varying percentages of ethylene glycol, later releases will include a wider range of incompressible fluids (liquid fuels) and compressible fluids (air).
