A practical process engineering solution for pipe sizing and pipe friction losses calculation for water, including valves and fittings (minor) losses. Features included:
- Internal and external diameters of the common commercial steel pipes for different schedules (thickness)
- Physical properties of water at given temperatures (density and viscosity)
- Calculations in two different systems of units – Metric and English (Imperial) – with usual units for piping calculations
Friction factor is calculated using the Colebrook-White formulae:
1/√f=-2*log((ε/D)/3.72+2.51/(Re*√f))
For laminar flow (Re<2000):
f=64/Re
Distributed head losses:
h_l=f*L/D*v^2/(2*g)
