Sizing an hydraulic system requires to take into account numerous data . The distribution of fluids, liquids or gases, air or water, are studied to provide the desired flow with minimum cost installation, maintenance and operation. Sizing ducts and the elements of the network must be done by taking into account the changing of flow rate. It may be wise to create graphics and save, print, to compare and argue the choice in a group decision.
The graphical analysis tool was created for this purpose and can test your Inventory pressure drop or head loss versus different flow rates.
Inventory of pressure drop or head loss calculated, appears at the bottom of screen , Here the user will perform a graphical analysis of network flow testing of 47 to 150 liters per minute
The graphs show: the proportion of losses by network elements, energy consumption and cost in euros of losses. If an item is sized wrong with this appear clearly on operating costs or loss of pressure.
This allows to visualize the consequences of the choice of material in terms of operating costs and create simulations of different networks to find the best compromise
To know the output flow (operating point) of a network powered by a tank taking into account losses in the network ,
We must know the operating curve of the shell and the curve of operation of our network.
The intersection of 2 curves gives us the operating point.
Calculate the pressure drop at a rate of approximately (unimportant because the flow will be reassessed)
elements of the section connected to your tank through the inventory of losses.
Save your inventory loss.
Open the graphical analysis (internal flow tools / graphical analysis) and load your registered section.
Curve of the shell (allows to know the max speed)
select "Search point operation"
select "fluid reservoirs"
Enter the height of liquid
Enter the hole diameter
click Create curved shell
click on "graphical analysis"
if it exists, your operating point appearson the graph .
In not that's mean the flow range is not compatible, we must resize the pump or the size of pipes, elements.....
A similar approach is used for determine the operating point or flow of a network connected to a pump or reservoir.
