Definition of the Circular Inch
A circular inch is the area of a circle with a diameter of 1 inch. The formula for calculating the area of a circle is:
Circular Inch Historical
The circular inch was introduced as a practical unit for measuring areas in contexts where circular cross-sections were common, such as:
- Pipe diameters
- Wire gauges
- Hydraulic and pneumatic systems
It instantly gained employment in engineering and manufacturing industries, especially in those areas of applications that entailed round features or hole measurement.
The circular inch, however, has no origin in the times of agriculture or the surveying of lands or parcels of land like the acre unit of measurement. It is relevant most to industrial and scientific purposes.
The circular inch is a relatively small unit, so its conversions to larger units of area are rarely used in practice. However, it can be expressed as:
1
circular inch = 0.7854
square inches1
circular inch ≈ 5.454 × 10⁻³
square feet1
circular inch ≈ 6.051 × 10⁻⁴
square yards1
circular inch ≈ 5.067 × 10⁻⁴
square centimeters
Use in Measurement Today
The circular inch remains relevant in engineering and manufacturing, particularly in the following areas:
- Hydraulics and Pneumatics: Employed in the determination of the area within cross section of pipes, cylinder and opens at a given moments. For use in calculation of fluid flow rates and pressure throughout various elements of a system.
- Wire and Cable Manufacturing: Usually used in the measurement of wire cross sections since circles are frequently the shapes of sections of wire.
- Mechanical Engineering: It used for designing and analyzing circular shaped members such as shafts, bearings, gears etc.
- Optics and Lenses: Proves quite valuable for designing circular openings and lens.
Notable Uses
- Industrial Design: The circular inch is useful for assessing the capacity and performances of circulation based systems that incorporate circular sections.
- Aerospace and Automotive: Applied in the construction of the engines, turbines and other round engine components.
- Electrical Engineering: Part of the process of defining the cross sectional area of wires thus affecting the current carrying capability.
Definition of the Barn
The barn is a unit of area used in nuclear physics to measure the amount of surface that two particles may interact, for example, neutrons colliding with atomic nuclei.
- 1 barn is defined as
10⁻²⁸
square meters. - This is perhaps the reason for choosing the name 'barn' - a playful reference to the saying 'hit the broad side of a barn'; Indeed, relative to the questions addressed in nuclear physics, this cross-sectional area might appear to be rather broad.
The barn is much too small to be relevant in macroscopic measurements, such as land or real estate.
Barn Historical
The barn was first developed in the early 1940s in the Manhattan Project. Nuclear fission researchers seeking to design cross-sectional areas of nuclei engaged in nuclear reactions required convenient geometry to use.
The term barn was proposed by professors of physics M.G. Holloway and R. Harvey who strived to have this unit have a simple name easy to memorize. While it was rather funny that the concept of a barn arose from bomb-making, it didn't take long for it to be adopted in nuclear physics because it made practical sense.
Conversion to Other Units
Since the barn is used in nuclear physics, its conversions relate to extremely small areas. For comparison:
1
barn = 10⁻²⁸
square meters1
barn = 10⁻²⁴
square centimeters1
barn ≈ 1.076 × 10⁻²⁷
square feet1
barn ≈ 1.196 × 10⁻²⁷
square yardsThese values highlight the incredibly small scale of the barn compared to everyday units of area.
Uses of the Barn Today
The barn remains an essential unit in nuclear physics and particle physics, particularly in the study of:
- Fusion and Fission Research: Understanding the interaction of particles in nuclear reactors and fusion experiments.
- Nuclear Reactions: Describing the probability of interactions between particles like neutrons, protons, and nuclei.
- Particle Scattering: Quantifying the cross-sectional areas of particles in accelerators and reactors.
- Astrophysics: Used in studies involving cosmic particles and their interactions with matter.
