archisoup is an online learning resource and platform for architecture students, young architects and enthusiasts. The word bar has its origin in the Ancient Greek word βάρος ( baros), meaning weight. The unit's official symbol is bar; the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as mb (rather than the proper mbar) to denote the millibar. Between 1793 and 1795, the word bar was used for a unit of weight in an early version of the metric system.

Gauge Pressure. When pressure is measured relative to atmospheric pressure (14.7 psi), it is called gauge pressure (psig). The term gauge pressure is applied when the pressure in the system is greater than the local atmospheric pressure, p atm. The latter pressure scale was developed because almost all pressure gauges register zero when open to the atmosphere. Gauge pressures are positive if they are above atmospheric pressure and negative if they are below atmospheric pressure. A scale bar if often calculated at the time of when the drawing or map is complete, and before it is plotted (printed) to a set size. If for example the drawing is being plotted to a metric 1:100 scale, and the scale bar units are in meters, then each one of its segments will represent 1 meter and be 100 times smaller than the 1 meter real-world measurement.

For example, a cold-drawn carbon steel round bar is stronger and more precise than a hot-rolled bar, making it ideal for applications where precision is key. On the other hand, the hot-rolled TG&P carbon steel round bar is more durable and easier to weld, making it a good choice for fabrication projects.

Particularly within the design, architectural, and engineering professions, in many instances drawings are printed to an exact size and can therefore be measured via a scale rule. The addition of a scale bar however means that the drawing can be measured using a traditional ruler and/or via any other well proportioned object such as a credit card or posit. The abbreviations "bar(a)" and "bara" are sometimes used to indicate absolute pressures, and "bar(g)" and "barg" for gauge pressures. This usage is deprecated and fuller descriptions such as "gauge pressure of 2 bars" or "2-bar gauge" are recommended.

What is Pressure

As we know, different countries have their own way to measure and record the reinforcing bar. To meet the needs of our customers, we display some rebar sizes charts so that it is easy to choose the most suitable rebar you wanted. This is particularly useful when measuring via a digital screen or mobile device, and when a plotter is not available to print the required paper size. Types Aside from making map and drawing reading easier, when a scale bar is present, the drawing or map doesn’t necessarily need to be printed to a specific size. This is because the scale bar, no matter how big or small the drawing becomes, maintains its proportion to the drawings subject. By night the venue becomes the place to be, with events such as pub quizzes and various themed club nights. Evening food includes delicious freshly made pizzas and pasta dishes. The carbon steel round bar is a versatile product that can be used in a wide range of applications. We offer it in various grades, each with its own set of properties and benefits.
