Frictionless Calc is an engineering calculation aid. It is not a substitute for project-specific engineering judgment, applicable codes and standards, or manufacturer data.
Use of results
Calculations are provided for informational and preliminary engineering purposes. Results depend on the accuracy of user inputs and on the assumptions and correlations described on the Methodology page.
Before using a result for equipment selection, safety-critical design, procurement, construction, regulatory compliance, or operation of a real system, independently verify the calculation and confirm that the selected methods are appropriate for the fluid, piping, fittings, and operating conditions involved.
