Pressure drop calculation

This calculator can be used for both laminar and turbulent flow regime. You can calculate pressure drop or flow rate through a pipe including friction losses and minor pressure losses calculation.

The most frequently used calculation in fluid dynamics probably is the calculation of pressure drop through a pipe or a channel. Also when the difference in pressure is known the same calculation is used to calculate possible flow rate through pipe.

Pressure drop calculator is based on the Bernoulli equation for calculation of pressure difference between two points of one stream line, including pressure losses due to friction and minor losses (like losses in bends, branches, valves etc.). The pressure difference due to change of height is not included in this version of calculator. Also this calculator can be used for flow through pipe calculation when pressure difference is known.
