Definition
- Noun:
- A graphic representation of numerical relations: A nomograph is a diagram, chart, or graph that allows the approximate graphical computation of a mathematical function or the solution of an equation. It typically consists of scales arranged so that a straight line drawn across them intersects the scales at values satisfying the equation.
Usage Examples
- Noun:
- The engineer used a nomograph to quickly determine the pressure drop in the pipe.
- This nomograph relates temperature, flow rate, and viscosity for the chemical process.
- Before digital calculators, nomographs were common tools for performing complex calculations.
Advanced Usage
"to construct a nomograph": To design and draw a nomographic chart for a specific equation or set of variables.
- The researcher's task was to construct a nomograph for the new thermodynamic model.
"to read from a nomograph": To obtain a value or result by interpreting the intersecting lines on the chart.
