THE FIRST APP FOR THE CALCULATION OF WATER HAMMER!!!

Simple and practical set of utilities for the calculation of water pipes.

Calculate the relationship between speed-flow-diameter.
Inputting two parameters, calculates the remaining. Very useful for example as a first test of the diameter calculation (setting the speed between 1-2 m / s or 3.3 to 6.5 ft / s)

Load Loss Calculation.
Based on Hazen-Williams formula incorporates the coefficients of different materials. Incorporates multiple outputs (same value) coeficient ( F Christiansen).

Inverse calculation.
Knowing the pressure drop (or Pressure available / slope), you can calculate the other parameters such as flow, diameter, length.

Calculation of water hammer.
Based on the calculation of downtime Mendiluce and Allievi formulas (fast closing) and Michaud (slow closing).

It includes:

- Metric and USA

- Extensive database of PVC, PE and Polyester pipes, European and PVC and PE pipes USA. Coming soon from other countries. Possibility to use custom pipeline.

- Hazen-Williams coefficients of different materials

- Wave speeds of the different types of pipes

- Water temperature to 20 ° C (68 º F), simplifies the calculations and avoids the use of unknown coefficients.
