Online software for calculating pipe size

Online software for calculating and determining the size of building pipes

Nowadays, the issue that is not considered at all is the size of the building pipes, honestly, the water pressure of the city to the door is about 2 times according to the publications and standards of the national building regulations!

2 times means 20 meters of water column, in other words, the water that is delivered to you by the province water and sewage company to the door with a pressure equivalent to 20 meters of water, that is, if your piping system is ideal and dreamy and there is no friction. Do not drop the pressure, this water will reach the height of 20 meters of your building by itself!

Now pay attention to this:

The size of the pipes and fittings is indirectly related to the pressure drop, which means that if the size decreases, the pressure drop will increase!

Well, in Iran, the size of the main pipe is usually considered to be 25 mm for 4-storey buildings, and this determination of the size of the pipe has no calculation basis and is only based on Rials!
This causes the water in these buildings to reach the second floor by force!

At that time, a pump is used to compensate, which increases the energy consumption of the building and thus the country!

Imagine all the houses in Tehran did not have pumps, how much would the energy consumption be reduced now?

Now do you think it would not be better to calculate the size of the pipe ourselves first?

If you doubt what I said, you can use this software to model a 4-story single-unit building yourself to see how much water pressure drops in the pipes!

Now let’s look at the software description:

In the pipe sizing software, you must first specify the number and type of equipment, and then on the last page, you can select any size of pipe you want, and the software only the speed and pressure drop of water in different types of galvanized pipes. , Shows you black metal, white plastic and black plastic!

Yes, you can compare the drop of different types of pipes and choose the most suitable size according to your opinion, of course, the basics are comparison with water velocity, ie the closer the water velocity in your pipe is, the better! h3>

Of course, you can also work in combination, that is, if you are going to pipe 10 meters, this 10 meters of pipe must not be the other, you can run this 10 meters with several sizes of pipes, only in the area of ​​pipes, this division Include classification for each size!
That is, if you want to work in two sizes, for example: consider 6 meters 40 mm and 4 meters 32 mm.
