Pipe diameter water pipe : to entrust the choice of professionals

Water supply in the country and in a country house

Sorry, as always, I prefer to start with a simple and banal advice, which you can not pay any attention to, if the house has a plumber with a thirty-year experience and golden hands.

1. Engineering plumbing system, for all its apparent simplicity - somewhere there is pressure in the supply manifold or operates stand-alone pumping station in personal well, so the water in the house should be, it does not always work.
2. simple, collapsible water for seasonal water supply does not require the selection and calculation of pipe diameter.Feel free to buy PE80 1/2 and plant on a site farm, watering, and entertainment network.Your
3. the feed water pipe system has a design flow rate of the water supply, set design costs for stations and water pumping units.Congratulations, you live in a good country cottage, which designed the experts.

And the third case is the funniest, as professionals who counted water supply system and install, can be mistaken not only in terms of diameters (working sections) pipes for water, but also from the scheme of their wiring.Terrible consequences for the water supply of private homes, commercial and residential buildings will not happen, but at the right moment can:

• not do the right amount of water in the washing machine;
• refuse favorite hose for washing machines;
• escape from overheated cold water baths, etc.

Therefore, for your own peace of mind alone decompose (invent) a scheme of water supply and begin to estimate by eye internal diameters and other performance characteristics of its bathing and laundry plant.

pipe diameter calculation for water

Our citizens love to invent the wheel, instead of it just to ride.All existing SNIP, state standards and specifications for pipe products have long been laid down in the charming settlement programs.Ready CAD (computer aided design) pipeline systems for any purpose (heating, ventilation, drainage, water supply) have been around for 40 years.It remains the invented somebody software to find and enter the required data.You say, for professionals such work is nothing, but what about me simple rural inhabitant.Initial data:

• settlement (best work) hydraulic pressure feed water supply systems, it would be: well, well with submersible pump or a collective main pipeline, does not matter;
• length of a dilution of autonomous water supply schemes;
• hydraulic resistance - a separate issue;
• the height of the water intake sites and their water consumption.

Add another ten parameters that can be found in building codes, and you can safely offer the services of a private plumber neighbors.

Inner diameter water pipes

Hydraulic resistance and stagnant water area of ​​private houses we have specially taken out in a separate paragraph.Suppliers and builders do not usually warn users about the specific tendencies of delivered products and some carelessly allowed their installation.

• coefficient of friction has not been canceled: polyethylene in a good performance in five or six years will handicap galvanizing steel of the same internal diameter;
• number of bends, tees and simply connecting fittings on the scheme of water supply system of pipes of any diameter should be kept to a minimum;
• quality of tap water in the penstock is desirable to support the filtering stations, or the inner diameter of the pipe overgrown mud and dirt;
• ratio of internal and external diameters of pipes for plumbing absolutely no effect on its performance, if it is made in accordance with the technical requirements and are certified.

Believe cottage water - a very simple hydraulic structure, provided that you do it correctly positioned in the head and a little self-calculated.
