Pressure

Pressure is a quantity that is numerically equal to the value of the force per unit area.

1 - Force.

2 - Pressure.

3 - Area.

Force = Pressure x Area

Pressure = Force / Area

Area = Force / Pressure

Pressure unit - Pascal [Pa]

If the force F = 1 Newton [N] acts on an area of ​​1 m2, the pressure will be 1Pa.

Water pressure is measured in bars. The quantity has an alternative name - atmospheric unit. Water with a pressure of 1 bar rises to a height of 10 meters.

According to various regulations for cold water, the pressure varies from 0.3 to 6 bar; for hot water - from 0.3 to 4.5 bar. This refers to the permissible limits of water pressure.

For optimum performance of all devices installed in the pipeline, overpressure of more than 6.5 bar is not recommended.

A pressure gauge is used to measure pressure; it is installed at the entry of water into the house.
