With FluidSys Demo you can calculate.

The piezometric height and loss pressure by friction, in straight pipes by Hazen Williams' s method and/or Darcy Weisbach´s method.

Calculate the reynolds´s number and relative roughness.

Loss pressure in hydraulic accessories such as:
elbows at 90 ° and 45 °,
T-Connections,
unions,
gate valves,
globe valves,
gradual and abrupt expansions,
gradual and abrupt contractions,
pipe outlet with rounded or straight edges,
pipe inlet with rounded or straight edges.

Calculate the equivalent pipe length for loss of pressure.

Calculate the equivalent pipe diameter for loss of pressure.
