Гидравлический расчет трубопро

In calculating water supply systems or heating you face the task of selection of the pipeline diameter. To solve this problem you need to do your calculation of hydraulic systems, and for even more simple solution - you can use the online hydraulic calculation, we will do now.

Operating procedure:

1. Select the appropriate calculation method (calculation tables Sheveleva theoretical hydraulics or SNIP 2.04.02-84)

2. Select the piping material

3. Set the current water flow in the pipeline

4. Set the outer diameter and pipe wall thickness

5. Set the length of the pipeline

6. Set the average water temperature

The result of the calculation is given below the graph and values ​​hydraulic calculation.

The schedule consists of two values ​​(1 - loss of water head, 2 - water speed). The optimal values ​​of the diameter of the pipe to be written in green below the graph.

Those. you must set the diameter so that the point on the graph has been severely over your green values ​​of the diameter of the pipeline, because it is only when these values ​​of the water velocity and pressure loss will be optimal.

The pressure loss in the conduit show the pressure loss in a predetermined section of the pipeline. The higher loss, the greater the need to make work to deliver the water to the right place.

Characteristic hydraulic resistance indicates how well matched the diameter of the tube depending on the pressure loss.
