Calculation the pressure drop in the design of liquid pipelines

This Hydraulic Calculator App is designed for calculation the pressure drop in the design of liquid, gas, two-phase fluid pipelines taking account of inline fittings (such as bends, valves and so on) will be carried out. The friction factor is calculated using Poiseuille's equation for laminar flow and Colebrook's equation for transitional and turbulent flows. The methods used for calculation fitting pressure loss are Darby's 3K method as it give the better curve fits for pressure loss vs K factor data for various fittings.

Calculation and Features

• Liquid: The density does not change with pressure drop. It is also assumed that the temperature drop is not significant to change the fluid density appreciably.

• Select Liquid & Gas from drop down list

• Select pipe schedule from drop down list

• Select pipe material from drop down list

• Unit Conversion: Mass Flow Rate, Volume Flow Rate, Temperature, Pressure, Density.
