Daniel Bernoulli was born on February 8, 1700, in Groningen in the Netherlands. He is the son of Mathematician Johann Bernoulli, who was an early developer of Calculus. Daniel took an interest in mathematics when he was just 7 years old. Although his father tried to dissuade him from focusing on mathematics due to the limited financial gain, Johann did tutor his son in calculus and theories of kinetic energy.

Daniel continued to show promise, attending Basel University at the age of 13, where he studied logic and philosophy. By the time he was 15 years old, he had completed his bachelor’s degree, and earned his master’s degree a year later. At the age of 23, he moved to Venice, Italy to learn medicine, but he couldn’t get away from mathematics, becoming a professor of a university in Venice a year later.

In 1738, Bernoulli published the book Hydrodynamica, where he first explained what we know as Bernoulli’s Principle. This is of particular interest to us at EXAIR, as many of our products operate off of this principle. It states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure. This is derived from the conservation of energy, where an increase in kinetic energy (speed) requires a corresponding reduction in potential energy (pressure).

When compressed air exits the precise slotted nozzle of our Super Air Knife, this induces a low pressure area, which speeds up and draws in ambient air. This air entrainment (at a ratio of 40:1) is what makes our Super Air Knives so efficient. This same effect can be witnessed with our Super Air Amplifiers, Super Air Nozzles, Super Air Wipes, as well as many other products.

If you would like to discuss your application, and how the Bernoulli Principle may be beneficial, feel free to give us a call!
