The easiest unknowns to obtain for making plots on the psychrometric chart are typically the dry bulb temperature, relative humidity, and wet bulb temperature. These parameters can often be measured directly using standard instruments like thermometers and hygrometers. Once any of these values are known, the other properties, such as specific humidity and enthalpy, can be calculated or derived from the chart, allowing for a comprehensive analysis of the air's thermodynamic properties.
Florence nighting gale invented the pie and the pie chart
The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801, where two such graphs are used according to WikiPedia Some sources say Florence Nightingale invented the Pie Chart in 1857, but in fact even the Florence Nightingale museum admits she did not. She was an amazing person, but unfortunately not the inventor of the pie chart.

Psychrometric charts are used to measure the physical and thermal properties of moist air. They are mainly used with greenhouses and livestock building troubleshooting.

The two unknowns that are easiest to obtain for making plots on the psychrometric chart are dry-bulb temperature and relative humidity. These parameters are usually measured directly or can be easily determined using standard instruments, allowing for quick and accurate plotting on the chart.
The properties of air and the water contained in it at different temperatures arranged in the form of a chart which is called a psychometric chart. In particular it shows the quantitative interdependence between temperature and humidity. It is useful in the planning, specification and monitoring of cooling systems.

A psychrometric chart is a graphical representation used to analyze the properties of air in relation to temperature, humidity, and other parameters. It helps visualize how these properties interact and impact processes like humidification. By using the chart, engineers and researchers can design and optimize systems for humidification based on the specific conditions of the air.
