The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history.
1732 – Henri Pitot discovers how to measure the pressure from the speed of a fluid using a Pitot tube. [13] 1738 – Daniel Bernoulli publishes Hydrodynamica discussing the mathematical relation between pressure and velocity of fluids according to Bernoulli's principle. [1] 1742 – Anders Celsius designs a thermometer with the Celsius scale.
Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [ 1 ] Heron studied the pressure of air and steam, described the first steam engine , and built toys that would spurt water, one of them known as Heron's fountain.
