Pressure drop calculator
Pressure drop calculator can be used for pressure drop and flow rate calculation of all newtonian fluids with constant density.
Pressure drop calculation is based on the Darcy-Weisbach equation for head loss due to friction in closed round or rectangle pipe. Calculation of friction factor is based on the Colbrook and White equation (1937). Local resistances factor K for valves, fittings, pipes contraction and enlargement should be entered in calculator. Values of local resistances for some fittings (tees, elbows, reducers) can be found in calculator itself, or you can calculate it with resistance coefficient calculator.
Pressure drop calculator can be used for both laminar and turbulent flow regime, as Reynolds number of flow is calculated and presented in results. Reynolds number itself you can calculate with Reynolds number calculator
Pressure difference due to change of height is not included in this version of calculator, but you can still calculate flow rate if you available head of fluid height enter as pressure difference.
For compressible flow pressure drop calculation you can use gas flow calculator
Pressure drop calculator requires JavaTM.
